The epigenetic control of E-box and Myc-dependent chromatin modifications regulate the licensing of lamin B2 origin during cell cycle
Recent genome-wide mapping of the mammalian replication origins has suggested the role of transcriptional regulatory elements in origin activation. However, the nature of chromatin modifications associated with such trans-factors or epigenetic marks imprinted on cis-elements during the spatio-temporal regulation of replication initiation remains enigmatic. To unveil the molecular underpinnings, we studied the human lamin B2 origin that spatially overlaps with TIMM 13 promoter. We observed an early G1-specific occupancy of c-Myc that facilitated the loading of mini chromosome maintenance protein (MCM) complex during subsequent mid-G1 phase rather stimulating TIMM 13 gene expression. Investigations on the Myc-induced downstream events suggested a direct interaction between c-Myc and histone methyltransferase mixed-lineage leukemia 1 that imparted histone H3K4me3 mark essential for both recruitment of acetylase complex HBO1 and hyperacetylation of histone H4. Contemporaneously, the nucleosome remodeling promoted the loading of MCM proteins at the origin. These chromatin modifications were under the tight control of active demethylation of E-box as evident from methylation profiling. The active demethylation was mediated by the Ten-eleven translocation (TET)-thymine DNA glycosylase-base excision repair (BER) pathway, which facilitated spatio-temporal occupancy of Myc. Intriguingly, the genome-wide 43% occurrence of E-box among the human origins could support our hypothesis that epigenetic control of E-box could be a molecular switch for the licensing of early replicating origins

KNOWLEDGE AND AWARENESS ABOUT ORAL CANCER AMONG UNDERGRADUATE DENTAL STUDENTS
ABSTRACTObjective: To assess the knowledge and awareness about oral cancer among undergraduate dental students.Methods: A validated questionnaire of 10 questions, regarding the basic knowledge and awareness about oral cancer was distributed among the3rd year, final year, and internship (5 year trainee) of undergraduate dental program in Saveetha Dental College and Hospital, Saveetha University,Chennai. The data extracted were tabulated, statistically analyzed, and results obtained.thResults: About 41% of participants were unaware about the treatment costs for oral cancer and 33% of them said that they do not inform the patientsabout the risk factors of oral cancer. 36% of participants were unsure about where to refer the patients with oral cancer. 96% of students preferred tohave more training toward oral cancer diagnosis methods and treatment options available.Conclusion: Although the basic knowledge of the students is good, it is not adequate enough and practices about risk factors had to be reinforcedamong these students so that they can help the patients in tobacco and alcohol cessation and contribute in the prevention of oral cancers. The dentalcurriculum for students should lay more emphasis on diagnostic and prognostic factors of oral cancer. Morbidity and mortality are likely to be reducedif future dentists know how to prevent and detect oral cancer.Keywords: Knowledge, Awareness, Oral cancer, Dental students
Congenital Generalised Hypertrophy of Feet
Local hypertrophy, gigantism or overgrowth of hand, foot,part of it (Macrodactyly) or of full extremity are commonlyseen in Klippel Trenaunay Parkes Weber Syndrome.However congenital generalized hypertrophy of feet is arare presentation and a search of the literature revealedone case report in a 25 year old female, a similar case isbeing presented here
Polio Rehabilitative Surgery Camps
Twenty two surgical polio camps were organized in 8 districts of Uttar Pradesh and Madhya Pradesh from January 2000 to May 2006. Over 8000 children were screened, and three groups were made for physiotherapy, calipers and those who needed surgical correction for their deformities. 3370 patients were advised physiotherapy, 2920 were given calipers while 1250 patients were operated. By and large bony operations were avoided. 96 % of cases had full correction of deformities and only 4 % of cases needed further physiotherapy before fitting of orthoses. Such rehabilitative surgical polio camps offer a ray of hope for these illiterate, ignorant and unfortunate patients to lead an independent respectable life
Management of pelvic fractures in dog
Pelvic fractures are common sequelae of major traumatic injury of dogs and cat which, comprise of at least 25% of all fractures in veterinary practice (Piermattei et al., 2006). Fracture of ilium, the most common fracture seen in the pelvis account for 46% of all pelvic fracture (Henry, 1985; De Camp, 2005). Whereas, acetabular fracture comprises 12 % of pelvic fractures in dogs (De Camp, 2005). In smaller dogs, most of the pelvic fractures recover without surgery. But immediate surgery is required within 72 hours if the fracture is unstable (Harasen, 2007). We hereby report the successful surgical management of unstable fracture of ilium and ischium of pelvis in a Spitz dog
Synthesis and Preliminary Pharmacological Evaluation of 2-[4-(Aryl substituted) piperazin-1-yl]-Nphenylacetamides: Potential Antipsychotics
Purpose: Arylpiperazines have been recognized as the largest and most diverse class of compounds exerting actions on the central nervous system with strong affinity for serotonin and dopamine receptors. We here report the synthesis of some novel arylpiperazines and their evaluation for possible antipsychotic properties.Methods: The target compounds 2-[4-(aryl substituted) piperazin-1-yl]-N-phenylacetamides (3a-j) were synthesized by first reacting aniline (1) in 2 N sodium hydroxide with chloroacetylchloride in dichloromethane to obtain 2-chloro-N-phenylacetamide (2) and subsequently treating with appropriatephenylpiperazine in acetonitrile in the presence of K2CO3 and KI. All the compounds were characterized by analytical and spectroscopic methods. The compounds were evaluated for antipsychotic activity using three animal models.Results: All the 10 new arylpipeazines showed variable antipsychotic activity with compound 3h being the least effective in the induction of catalepsy. Their effect may involve interaction with 5-HT2A and D2 receptors.Conclusion: A synthetic method and possible antipsychotic effect have been established for 2-[4-(Aryl substituted) piperazin-1-yl]-N-phenylacetamides.Keywords: N-phenylacetamide, Arylpiperazines, Antipsychotic activity, 5-HT2A, D2 antagonists
ALTERNATIVE HERBAL DRUGS USED FOR TREATING HAIR DISEASE
Objective: The main objective of present study is to treat Alopecia. Alopecia areata is an unpredictable hair-loss condition. Alopecia is a dermatological disorder with psychosocial implications on patients with hair loss. Herbal systems of medicine have become increasingly popular in recent years. Medicinal plants have been used for the treatment of hair diseases since antiquity. Herbs such as turmeric, fenugreek, ginger, Cyperus rotundus (Nagarmotha), and holy basil are integral parts of ayurvedic formulations. Cyperus rotundus is a well-known ayurvedic herb with purported claims of hair growth promotion.ĆĀ Methods: Extracts are prepared by separating the soluble matter from vegetable tissues by the application of a suitable solvent such as alcohol, water, or ether. The resultant liquid is concentrated by evaporation to obtain a liquid extract or concentrated almost to dryness to obtain the solid extract and its volatile oil. Hair formulation of Cyperus rotundus belonging to family Cyperaceae in the form of herbal formulation (5% herbal cream and oil) was studied and it showed excellent hair growth activity with standard (2% minoxidil ethanolic solution) in Wister albino rats.ĆĀ Results: Hair growth initiation time was significantly reduced to half on treatment with the oil, as compared to control animals. The hair growth promoting effect was evaluated against the control, standard, and test animals at 0, 10, 15, and 20 days with the formulated hair oil and hair cream prepared from the volatile oil extracted from the Cyperus rotundus and the significant hair growth was observed, and the growth was compared with the standard drug used 2% solution of minoxidil.ĆĀ Conclusion: The results of treatment with oil were better than the positive control minoxidil 2% treatment. It holds the promise of potent herbal alternative for minoxidil.ĆĀ Keywords: Alopecia areata, Cyperus rotundus, Hair growth, Extracts, Herbal creams, Hair oil, Hair formulation, Ayurvedic, Cyperaceae.ĆĀ ĆĀ ORCID iD: - http://orcid.org/0000-0002-0439-606
