Mental health problems like depression, cognitive impairment, anxiety, sleep disorders, and so on, arising out of senility, neurosis, and living conditions are common in the geriatric population.
To study the psychiatric morbidity among the rural elderly.
Settings and Design:
A community-based, cross-sectional study.
Materials and Methods:
A study was conducted on 800 rural elderly subjects, aged 60 years and more, living in ten randomly selected villages, served by the Rural Health Training Center (RHTC), Valadi, in Tamilnadu state, India. Cognitive functioning was assessed by the Mini Mental Status Examination (MMSE), and the depression by the Geriatric Depression Scale — Shorter version.
The data was analyzed with SPSS 16 version statistical software using proportions, and the chi-square.
A majority of the subjects were widows / widowers, illiterates, living with family, and showing economic dependency. The prevalence of cognitive impairment was 43.25%, with a mean MMSE score of 23.32±4.4, and the depression was 47.0% and 6.16±3.4. Cognitive impairment, depression, and a disturbed sleep pattern were associated with female sex, age, illiteracy, poverty, loneliness, and the low socioeconomic status of the family.
The study showed a definite association between the sociodemographic factors and psychiatric morbidity. Encouraging the Non-governmental Organizations (NGOs) working for the elderly, running of separate geriatric clinics, and effective implementation of schemes like old age pension are some of the measures to be taken.

Epidermoid cysts are developmental, benign, cutaneous cysts which are commonly found on face followed by trunk and neck. They account for approximately 80% of follicular cysts of the skin. They are slow growing lesions and remain asymptomatic until or unless secondarily infected. They occasionally have tendency to develop into a malignancy. We describe a case of giant epidermoid cyst of posterior part of external ear, a location where very few cases have been reported in the literature. Since cyst was attached to the external ear, esthetics was also one of the important concern apart from the cyst getting infected, as they cause disfigurement of the face. The cyst was excised surgically. Histopathology confirmed the presumptive diagnosis of Epidermoid cyst. Two-years after the resection there was no recurrence. Due to the possibility of the cyst to transform into a malignancy and for appropriate diagnosis, histopathological examination remains a gold standard for confirmatory diagnosis.

Objective: Patients with an oral ulcer may present initially to a general physician or a dental practitioner. Majority of the ulcers are benign and resolve spontaneously but small proportions are malignant. The aim of the present study was to determine the prevalence of recurrent aphthous ulcerations in the Indian population.
Material and Methods: 3244 patients attending the Department of Oral Medicine and Radiology during the period from November, 2010 to December, 2012 with various complaints were examined. Of the patients examined 1669 were females and 1575 were males.
Results: 705 patients presented with recurrent aphthous ulceration (21.7%). Females (56.3%) were more commonly affected than males (43.7%). Patients in the third and fourth decade were most commonly affected. Stress was the most common factor associated with recurrent aphthous stomatitis (386 patients). 54.5% patients did not take any medications and 72.9% patients opined that the condition needed no dental consultation.
Conclusion: The results of the present study indicate that recurrent aphthous ulceration is a common mucosal disorder in the Indian population. The early and proper diagnosis of the ulcers will help the dental practitioner in providing information to the patient regarding awareness and management of the condition.

The photocatalytic degradation has been considered to be an efficient process for the degradation of organic pollutants, which are present in the effluents released by industries. The photocatalytic bleaching of cationic dye methylene blue was carried out spectrometrically on irradiation of UV light using Cu(II), Ni(II), and Co(II) complexes of (2E)-2-[(2E)-3-phenylprop-2-en-1-ylidene]hydrazinecarbothioamide (HL). The effects of pH and metal ion were studied on the efficiency of the reaction. Cu(II) complex shows better catalytic activity and the highest percentage degradation (~88.8%) of methylene blue was observed at pH 12. A tentative mechanism has also been proposed for the photocatalytic degradation of methylene blue.
The Arabidopsis Ca2+/calmodulin (CaM)-binding transcription factor SIGNAL RESPONSIVE1 (AtSR1/CAMTA3) was previously identified as a key negative regulator of plant immune responses. Here, we report a new role for AtSR1 as a critical component of plant defense against insect herbivory. Loss of AtSR1 function impairs tolerance to feeding by the generalist herbivore Trichoplusia ni as well as wound-induced jasmonate accumulation. The susceptibility of the atsr1 mutant is associated with decreased total glucosinolate (GS) levels. The two key herbivory deterrents, indol-3-ylmethyl (I3M) and 4-methylsulfinylbutyl (4MSOB), showed the most significant reductions in atsr1 plants. Further, changes in AtSR1 transcript levels led to altered expression of several genes involved in GS metabolism including IQD1, MYB51 and AtST5a. Overall, our results establish AtSR1 as an important component of plant resistance to insect herbivory as well as one of only three described proteins involved in Ca2+/CaM-dependent signaling to function in the regulation of GS metabolism, providing a novel avenue for future investigations of plant–insect interactions.

A substantial proportion of patients with severe mental disorders remain untreated in India. Qualitative research has highlighted the complex interplay of multiple factors that preclude schizophrenia patients in rural Indian settings from accessing treatment.
(a) To establish the face and content validities of an interview schedule titled “Schedule of Factors Influencing Access (SOFIAc) to Psychiatric Treatment in Persons with Schizophrenia”, which comprehensively assesses the factors that prevent schizophrenia patients from accessing psychiatric treatment. (b) To assess the feasibility of its administration.
Materials and Methods:
SOFIAc contains 15 items. This schedule involves three phases of interviewing patients and family members. This was given to 12 experts. They used Likert scales (1=not at all satisfactory to 5=very much satisfactory) to rate each item of the schedule. In addition, the experts rated (the same way as above) the following five dimensions of the schedule (as a whole) separately: A (comprehensiveness of the factors), B (scoring system), C (interviewing method), D (general instructions given to the raters), E (overall schedule). Later on, 10 persons with schizophrenia were interviewed with SOFIAc to test the feasibility of administration.
Thirteen items were rated as either satisfactory (score=4) or very much satisfactory (score=5) by all 12 experts; remaining two were rated as 4 or 5 by 11 experts. Regarding comprehensiveness of the factors, scoring methods and general instructions given to the interviewers, all provided scores >4; regarding the method of interviewing, 11 provided the score of >4; with regard to overall interview schedule, all experts provided scores >4. Pilot testing revealed that it took 60 min to administer SOFIAc.
SOFIAc has satisfactory face and content validities. It is also feasible to administer SOFIAc.

Background and Objectives:
Initial research has shown a positive correlation between the severity of periodontal disease (PD) and prostaglandin E2 (PGE2) concentrations in gingival crevicular fluid (GCF). However, there are no enough reports to correlate the PGE2 concentrations in GCF in periodontal health, disease and after treatment. Hence, the present study is aimed to estimate the levels of PGE2 in GCF in periodontal health, disease and after periodontal therapy.
Materials and Methods:
A periodontal examination and collection of GCF by extracrevicular method was performed in 25 subjects selected randomly and categorized into three groups on the basis of plaque index, gingival index, probing pocket depth and clinical attachment level. Group I (healthy) consists of 10 subjects, Group II (chronic periodontitis) consists of 15 patients and Group III (after treatment group) consists of 15 patients of Group II. PGE2 levels were estimated in GCF samples by using the enzyme linked immunosorbent assay.
All clinical parameters improved significantly after therapy (P < 0.001). PGE2 was detected in all the samples. Highest mean PGE2 concentrations in GCF were obtained for Group II while the lowest concentrations were seen in Group I and Group III. Statistically significant difference was found between the levels of PGE2 at Group-II and Group-III (P < 0.05).
There is a substantial increase in the concentrations of PGE2 as PD progresses. Since PGE2 levels in GCF are positively correlated with gingival index, plaque index, probing pocket depths and clinical attachment levels, PGE2 may be considered as a Novel Biomarker in PD progression. However, controlled, longitudinal studies are needed to confirm this possibility.

Considering the role of matrix metalloproteinase-3 (MMP-3) and tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) in the pathogenesis of periodontitis, the present study is to estimate the levels of MMP-3 and TIMP-1 in gingival crevicular fluid (GCF) in periodontal health, disease and to evaluate the effect of periodontal therapy on MMP-3 and TIMP-1 concentrations in GCF.
Materials and Methods:
A periodontal examination and collection of GCF by extra-crevicular method was performed in 30 subjects selected randomly and categorized into 3 groups. Group I consists of 10 subjects Group II consists of 20 patients and Group III consists of 20 patients of Group II. Non surgical periodontal therapy was performed, and GCF was collected after 8 weeks from the same site of 20 chronic periodontitis patients who are considered as Group III. MMP- 3 and TIMP-1 levels were estimated in GCF-samples by using enzyme-linked immunosorbent assay. The findings were analyzed using the software and descriptive statistical methods such as Mann- Whitney U-test and Kruskal-Wallis test. P value < 0.001 was considered significant.
MMP-3 and TIMP-1 was detected in all samples. Highest mean MMP-3 concentrations in GCF were obtained for Group II (7.490 ng/ml) while the lowest concentrations were seen in Group I (0.344 ng/ml) and Group III (2.129 ng/ml). This suggests that MMP-3 levels in GCF increases proportionally with the progression of periodontal disease and decreases after treatment. Lowest mean TIMP-1 concentrations in GCF were obtained for Group-II (1.592 ng/ml), while the highest concentrations were seen in Group-I (8.78 ng/ml) and Group-III (6.40 ng/ml). This suggests that TIMP-1 levels in GCF decreases proportionally with progression of periodontal disease and increases after treatment.
There is a substantial increase in the concentrations of MMP-3 and decrease in TIMP-1 as periodontal disease progress. Since MMP-3 and TIMP-1 levels in GCF are positively correlated with gingival index, probing pocket depth, and clinical attachment loss, MMP-3, and TIMP-1 may be considered as a Novel Biomarkers in periodontal disease. However, controlled, longitudinal studies are needed to confirm this possibility.

A 19-year-old woman was diagnosed with osteogenesis imperfecta (OI). She had sustained numerous low-trauma fractures throughout her childhood, including a recent pelvic fracture (superior and inferior ramus) following a low-impact fall. She had the classical blue sclerae, and dual energy X-ray absorptiometry (DEXA) bone scanning confirmed low bone mass for her age in the lumbar spine (Z-score was −2.6). However, despite these classical clinical features, the diagnosis of OI had not been entertained throughout the whole of her childhood. Sequencing of her genomic DNA revealed that she was heterozygous for the c.3880_3883dup mutation in exon 50 of the COL1A1 gene. This mutation is predicted to result in a frameshift at p.Thr1295, and truncating stop codon 3 amino acids downstream. To our knowledge, this mutation has not previously been reported in OI.
OI is a rare but important genetic metabolic bone and connective tissue disorder that manifests a diverse clinical phenotype that includes recurrent low-impact fractures.Most mutations that underlie OI occur within exon 50 of the COL1A1 gene (coding for protein constituents of type 1 pro-collagen).The diagnosis of OI is easily missed in its mild form. Early diagnosis is important, and there is a need for improved awareness of OI among health care professionals.OI is a diagnosis of exclusion, although the key diagnostic criterion is through genetic testing for mutations within the COL1A1 gene.Effective management of OI should be instituted through a multidisciplinary team approach that includes a bone specialist (usually an endocrinologist or rheumatologist), a geneticist, an audiometrist and a genetic counsellor. Physiotherapy and orthopaedic surgery may also be required.
Dental caries is essentially a process of diffusion and dissolution. If the aspect of dissolution can be curtailed some degree of prevention can be achieved.
The present study was carried out to evaluate and compare the effect of Er:YAG laser and Co2 laser irradiation combined with acidulated phosphate fluoride treatment on in vitro acid resistance of human enamel.
An in vitro study was carried out on 30 human premolars to evaluate the enamel's acid resistance using an atomic emission spectrometry analysis.
Materials and Methods:
A total of 60 enamel specimens were prepared from 30 human premolars and were randomly assigned to 6 groups: (1) Untreated (control); (2) 1.23% acidulated phosphate fluoride (APF) gel application alone for 4 min; (3) Er:YAG laser treatment alone; (4) Co2 laser treatment alone; (5) Er:YAG laser + APF gel application; (6) Co2 laser + APF gel application. The specimens were then individually immersed in 5 ml of acetate buffer solution (0.1 mol/L, pH 4.5) and incubated at 37°C for 24 h, and the acid resistance was evaluated by determining the calcium ion concentration using the atomic emission spectrometry.
An ANOVA model was constructed (P value of 0.05), followed by Tukey's test for multiple pair wise comparisons of mean values.
Significant differences were found between the control group and the test groups (P < 0.001).
Combining acidulated phosphate fluoride with either Er:YAG or Co2 laser had a synergistic effect in decreasing the enamel demineralization more than either fluoride treatment or laser treatment alone.

Several techniques have been proposed for clinical crown lengthening procedures. Crown lengthening in esthetic zone can be classified in two basic types: Restorative and non-restorative cases after the crown lengthening is executed.
Atraumatic surgical extrusion using a specially designed instrument called periotome was performed in four cases on isolated teeth in esthetic zone.
The technique presented is an alternative approach to periodontal surgical procedures consisting orthodontic extrusion and osseous recontouring. It does not result in functional or esthetic deformities especially in the anterior esthetic zone.

Lymphatic Filariasis is a mosquito transmitted disease, caused by parasitic worm Wuchereria bancrofti. Global Programme for Elimination of Lymphatic Filariasis was established in early 2000. The strategy recommended by the World Health Organization is annual Mass Drug Administration (MDA) of single-dose of Diethylcarbamazine 6 mg/kg (DEC), distributed to inhabitants of Filariasis endemic areas, excluding children below 2 years of age, pregnant women, and seriously ill persons, and Morbidity Management. The health system distributes the drugs by a door-to-door strategy.
To assess the coverage and compliance of MDA in Bidar district during the campaign in November 2008.
Materials and Methods:
Cross-sectional population-based house-to-house visit. Outcome is assessed as actual coverage and compliance, in Percentage and proportions.
Eight clusters, total eligible population of 1 131 individuals were interviewed. The coverage rate was 78% with variation across different areas. The compliance with drug ingestion was 68%.
The effective coverage was below the target (85%). Side effects of DEC were minimum, the overall coverage was better in rural areas compared with urban areas.

Initial research has shown a positive correlation between the severity of periodontal disease and matrix metalloproteinase-3 (MMP-3) concentrations in gingival crevicular fluid (GCF). However, there are no enough reports to correlate the MMP-3 concentrations in GCF in periodontal health, disease and after treatment. Hence, the present study is to estimate the levels of MMP-3 in GCF in periodontal health, disease and to evaluate the effect of periodontal therapy on MMP-3 concentrations in GCF.
Materials and Methods:
Periodontal examination and collection of GCF by extracrevicular method was performed in 30 subjects selected randomly and categorized into three groups. Group I (Healthy, n=10), group II (Chronic periodontitis, n=20) and group III (After treatment group, n=20). Scaling and root planing (SRP) was performed and GCF was collected after 8 weeks of treatment. MMP-3 levels were estimated in GCF samples using enzyme linked immunosorbent assay (ELISA).
MMP-3 was detected in all samples. Highest mean MMP-3 concentrations in GCF were obtained for group II (7.490 ng/ml), while the lowest concentrations were seen in group I (0.344 ng/ml) and group III (2.129 ng/ml). This suggests that MMP-3 levels in GCF increases proportionally with the progression of periodontal disease and decreases after treatment.
There is a substantial increase in the concentrations of MMP-3 as periodontal disease progresses. Since MMP-3 levels in GCF are positively correlated with gingival index, probing pocket depth and clinical attachment level, MMP-3 may be considered as a “novel biomarker” in periodontal disease progression. However, controlled, longitudinal studies are needed to confirm this possibility.

Giant cell granuloma (GCG) is an uncommon bony lesion in the head and neck region, most commonly affecting the maxilla and mandible and has a female predilection. The clinical behavior of central GCG ranges from a slowly growing asymptomatic swelling to an aggressive lesion. The clinical, radiological, histological features and management of an aggressive GCG of maxilla in an 18-year-old female patient are described and discussed. It is emphasized that surgery is the traditional and still the most accepted treatment for GCG. Le Fort I osteotomy has been advocated as one of the access osteotomy for the surgical management of aggressive and extensive GCG involving the maxilla. The postoperative morbidity and recurrence have been discussed.

The aim of the present study was to estimate and compare the microleakage of a pit and fissure sealant after etching and Er:YAG laser treatment.
Materials and Methods:
Twenty non-carious premolars extracted for orthodontic reasons were equally divided into two groups. Samples in Group- I were treated with 37% phosphoric acid. Samples in Group II were irradiated with Er: YAG laser at 400 mJ at 4 Hz. Sealant was placed and light cured. Then, the samples were subjected to thermocycling. The samples were then immersed in 1% methylene blue. The samples were sectioned and examined under stereomicroscope at ×10 magnification.
Acid etched samples showed significantly less microleakage when compared to laser etching and it was statistically significant (P<0.01).

Hospital based cross-sectional study. The study participants were selected through purposive sampling. The study participants comprised 316 men and women above 20 years of age from a disease-free cohort and included healthy subjects visiting the lifestyle clinic of CARE Hospitals, Hyderabad, India for health check-up.
Among the participants of the study, 28.5% of the males and 42.2% of the females had hypercholesterolaemia. Body weight was significantly associated with total cholesterol and low-density lipoprotein (LDL) cholesterol. Of the subjects studied, males had a higher mean calorie and fat intake than the females. A positive association was observed between waist circumference and both total cholesterol and LDL cholesterol. Waist circumference was also positively correlated with systolic and diastolic blood pressure and triglycerides. There was a significant difference in the total cholesterol levels of subjects who exercised and those who were not involved in any physical activity. There was a significant difference between the high-density lipoprotein (HDL) cholesterol values of the subjects based on exercise levels. High-density lipoprotein cholesterol levels were significantly higher in males than in females and this is corroborated by the finding of increased exercise levels in males. Duration of exercise had a significant impact on the total cholesterol levels.
Our results confirm that diet and exercise routines significantly affect the serum lipid profile. Obesity and overweight constitute a risk factor for the development of hypercholesterolaemia and hypertriglyceridaemia.

A fibroblast growth factor 2 (FGF2)-targeted adenoviral system can alter viral tropism and allow for improved transduction and reduced systemic toxicity. This study is to investigate if the FGF2-targeted adenoviral mutant Nijmegen breakage syndrome 1 (FGF2-Ad-NBS1) gene transfer can enhance cisplatin chemosensitisation not only by targeting DNA repair, but also through the induction of antiangiogenesis, whereas at the same time reducing toxicities in treating head and neck squamous cell carcinoma (HNSCC).
The human HNSCC cell line was treated in vitro and in a nude mouse xenograft model. We conducted verification of binding ability of mutant NBS1 and downregulation of MRN complex, evaluation of transduction efficiency and combined antitumour activities. The antiangiogenesis mechanism was also investigated. Finally, we estimated the distribution of adenoviral vector in the liver.
The mutant NBS1 protein retains the binding ability and effectively suppresses the expression level of the MRN in infected cells. Transduction efficiency in vitro and cisplatin chemosensitisation were upregulated. The FGF2-Ad-NBS1 also showed detargeting the viral vectors away from the liver. The downregulation of NF-κB expression was supposed to correlate with increased antiangiogenesis.
FGF2-targeted adenoviral system enhances the cisplatin chemosensitisation of mutant NBS1 and may avoid viral-associated liver toxicities.

To determine whether the frequency and amplitude of vibration and the use of surfactant has any effect on the formation of voids on the cast surface, poured from a polyvinyl siloxane impression material, using a mechanical model vibrator.
Materials and Methods:
A total of 100 impressions of a master die were made using Reprosil, Type 1, Medium Viscosity, Regular body, and Dentsply Caulk. The test group was subdivided into a surfactant and non-surfactant group, 50 impressions each. The impressions were poured in a dental stone with a mechanical model vibrator that was set at a vibration frequency of 3000 cycles / minute (low) and 6000 cycles / minute (high) with the help of a knob. The resultant casts were examined with a Stereomicroscope (LABOMED CZM4) under ×10 magnifications.
For the low and high frequencies, when surfactant and non-surfactant groups were compared, for all the amplitudes and for both the material groups, the surfactant groups resulted in fewer void formations and showed very high statistical significance (P-value = 0.001).
The lowest mean voids were obtained for high frequency surfactant groups. Reprosil: High frequency amplitude 2 being the most prominent, produced the least mean voids (mean = 23.2000, P = 0.001, very highly significant). In comparison, the surfactant groups produced the least voids for both frequencies.

Family–work conflict (FWC) and work–family conflict (WFC) are more likely to exert negative influences in the family
domain, resulting in lower life satisfaction and greater internal conflict within the family. Studies have identified several
variables that influence the level of WFC and FWC. Variables such as the size of family, the age of children, the work
hours and the level of social support impact the experience of WFC and FWC. However, these variables have been
conceptualized as antecedents of WFC and FWC; it is also important to consider the consequences these variables have
on psychological distress and wellbeing of the working women.
to study various factors which could lead to WFC and FWC among married women employees.
Materials and Methods:
The sample consisted of a total of 90 married working women of age between 20 and 50 years. WFC and FWC Scale was administered to measure WFC and FWC of working women. The obtained data were analyzed using descriptive and inferential statistics. Carl Pearson's Correlation was used to find the relationship between the different variables.
Findings and Conclusion:
The findings of the study emphasized the need to formulate guidelines for the management of WFCs at organizational level as it is related to job satisfaction and performance of the employees.

Of all the aneurysmal bone cysts (ABC) occurring in the body, less than 1% are seen in the patella. We report here, a 27-year-old woman with Stage III ABC of patella. Curettage, chemical and thermal cautery of the bed followed by autogenous bone grafting of the defect was done. At two-year follow up, there was a suspicion of lucency in the middle of the patella. However a repeat curettage revealed only fibrous tissue. Now at four years of follow up, the bone graft remained well incorporated. Patient has mild anterior knee pain on stair climbing but regained normal knee function.

U1-70K, a U1 snRNP-specific protein, and serine/arginine-rich (SR) proteins are components of the spliceosome and play critical roles in both constitutive and alternative pre-mRNA splicing. However, the mobility properties of U1-70K, its in vivo interaction with SR proteins, and the mobility of the U1-70K-SR protein complex have not been studied in any system. Here, we studied the in vivo interaction of U1-70K with an SR protein (SR45) and the mobility of the U1-70K/SR protein complex using bimolecular fluorescence complementation (BiFC) and fluorescence recovery after photobleaching (FRAP). Our results show that U1-70K exchanges between speckles and the nucleoplasmic pool very rapidly and that this exchange is sensitive to ongoing transcription and phosphorylation. BiFC analyses showed that U1-70K and SR45 interacted primarily in speckles and that this interaction is mediated by the RS1 or RS2 domain of SR45. FRAP analyses showed considerably slower recovery of the SR45/U1-70K complex than either protein alone indicating that SR45/U1-70K complexes remain in the speckles for a longer duration. Furthermore, FRAP analyses with SR45/U1-70K complex in the presence of inhibitors of phosphorylation did not reveal any significant change compared to control cells, suggesting that the mobility of the complex is not affected by the status of protein phosphorylation. These results indicate that U1-70K, like SR splicing factors, moves rapidly in the nucleus ensuring its availability at various sites of splicing. Furthermore, although it appears that U1-70K moves by diffusion its mobility is regulated by phosphorylation and transcription.
Northeast India, the only region which currently forms a land bridge between the Indian subcontinent and Southeast Asia, has been proposed as an important corridor for the initial peopling of East Asia. Given that the Austro-Asiatic linguistic family is considered to be the oldest and spoken by certain tribes in India, Northeast India and entire Southeast Asia, we expect that populations of this family from Northeast India should provide the signatures of genetic link between Indian and Southeast Asian populations. In order to test this hypothesis, we analyzed mtDNA and Y-Chromosome SNP and STR data of the eight groups of the Austro-Asiatic Khasi from Northeast India and the neighboring Garo and compared with that of other relevant Asian populations. The results suggest that the Austro-Asiatic Khasi tribes of Northeast India represent a genetic continuity between the populations of South and Southeast Asia, thereby advocating that northeast India could have been a major corridor for the movement of populations from India to East/Southeast Asia.
