Aim: Assessment of mast cells density expression in oral premalignant and malignant lesions by histochemical analysis.
Materials And Methods: The study used a total of 120 tissue blocks that were formalin-fixed and paraffin-embedded. These blocks consisted of 40 cases of oral squamous cell carcinoma (OSCC), 40 cases of oral epithelial dysplasia, and 40 cases of normal oral mucosa (NOM).
The circadian system plays a crucial role in regulating metabolic homeostasis at both systemic and tissue levels by synchronizing the central and peripheral clocks with exogenous time cues, known as zeitgebers (such as the light/dark cycle). Our body's behavioral rhythms, including sleep-wake cycles and feeding-fasting patterns, align with these extrinsic time cues. The body cannot effectively rest and repair itself when circadian rhythms are frequently disrupted.

Context: Odontogenic cysts and tumours are a wide array of complex pathological entities ranging from mild indolent to aggressive detrimental in nature, which occur as a result of anomalous alterations in normal odontogenesis. Hence, these odontogenic lesions need to be evaluated extensively by using potential immunohistochemical markers.
Aim: To evaluate and compare the expression of podoplanin, a lymphoendothelial IHC marker in odontogenic cysts and odontogenic tumours to determine their proliferative potential.
Background: The prevalence of oral cancer and other oral premalignant diseases (OPMDs) is increasing. Particularly among lower socioeconomic countries, awareness with respect to oral cancer is quite poor. The aim of the current study is to evaluate the level of awareness of patients about existing oral precancerous lesions.

Nonalcoholic steatohepatitis (NASH) is considered a pivotal stage in nonalcoholic fatty liver disease (NAFLD) progression and increases the risk of end-stage liver diseases such as fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). The etiology of NASH is multifactorial and identifying reliable molecular players has proven difficult. Presently, there are no approved drugs for NASH treatment, which has become a leading cause of liver transplants worldwide.

The aim of this study was to compare the accuracy, specificity and sensitivity of four commonly used methods of dental age estimation in a sample of south Indian adolescents and young adults aged between 14 and 30 years, with an age threshold of 18 years, using receiver operating characteristic curves (ROC) and the area under the curve (AUC). A total of 1070 orthopantomograms (535 males and 535 females) of adolescents and young adults of south Indian origin were collected retrospectively and interpreted. The effectiveness of each method was evaluated by using sensitivity (Se), specificity (Sp), likelihood ratios (LR+ and LR-) and AUC.

Non-alcoholic steatohepatitis (NASH) is a clinically important spectrum of non-alcoholic fatty liver disease (NAFLD) in humans. NASH is a stage of NAFLD progression wherein liver steatosis accompanies inflammation and pro-fibrotic events. Presently, there are no approved drugs for NASH, which has become a leading cause of liver transplant worldwide.

The hepatic mevalonate (MVA) pathway, responsible for cholesterol biosynthesis, is a therapeutically important metabolic pathway in clinical medicine. Using an unbiased transcriptomics approach, we uncover a novel role of Unc-51 like autophagy activating kinase 1 (ULK1) in regulating the expression of the hepatic cholesterol biosynthesis/MVA pathway genes. Genetic silencing of ULK1 in non-starved mouse (AML-12) and human (HepG2) hepatic cells as well as in mouse liver followed by transcriptome and pathway analysis revealed that the loss of ULK1 expression led to significant down-regulation of genes involved in the MVA/cholesterol biosynthesis pathway.

In the present study, we reported the role of autophagy flux in microglia activation, neurobehavioral function and neuronal death using a mouse model of JEV. Markers for autophagy (LC3-II/I, SQSTM1/P62, phos-Akt, phos-AMPK), and neuronal death (cleaved caspase 12, H2Ax, polyubiquitin) were investigated by western blot at 1, 3 and 7 days post inoculation.

Hence, a cross-sectional study was conducted to evaluate clinical and oral presentations of patients coinfected with HIV-TB, correlating with various parameters such as the type of TB with CD4 cell count, the type of TB with oral manifestations, site of the lesion, oral manifestations with CD4 cell counts, age, and gender.
Materials And Methods: A cross-sectional study was conducted among selected 200 patients coinfected with HIV-TB, registered at Gandhi Medical College, Hyderabad, Telangana, India, and demographic data, CD4 count, diagnosis of TB, and clinical presentation of TB were correlated with site, age, gender, and the type of lesions in the oral cavity.
Non-alcoholic fatty liver disease (NAFLD) and its advanced complication, non-alcoholic steatohepatitis (NASH), have become leading causes of hepatocellular carcinoma (HCC) worldwide. In this review, we discuss the role of metabolic, gut microbial, immune and endocrine mediators which promote the progression of NAFLD to HCC. In particular, this progression involves multiple hits resulting from lipotoxicity, oxidative stress, inhibition of hepatic autophagy and inflammation.

Here, we explored the molecular mechanism in an ovariectomized (OVX) rat model, hypothesizing participation of autophagy and growth factor signaling that relate with apoptosis. We observed enhanced hippocampal autophagy in OVX rats, characterized by increased levels of autophagy proteins, presence of autophagosomes and inhibition of AKT-mTOR signaling.

Time-restricted feeding (TRF), wherein food consumption is restricted to the metabolically active phase of the day, is a dietary approach that improves metabolic parameters when consuming a high-fat diet (HFD). Here, we tested whether TRF could reduce maternal HFD associated inflammation and thereby mitigate defects in fetal organ developmental.

To explore novel transcriptional pathways regulated by lysosomes, we performed microarray analysis followed by qPCR validation in a mouse hepatocyte cell line, AML12, treated with bafilomycin A (lysosomal v-type H-translocating ATPase inhibitor). Pathway enrichment analysis revealed significant downregulation of gene sets related to peroxisomal biogenesis and peroxisomal lipid oxidation upon lysosomal inhibition.

Thyroid hormones (TH) of maternal origin are crucial regulator of mammalian brain development during embryonic period. Although maternal TH deficiency during the critical periods of embryonic neo-cortical development often results in irreversible clinical outcomes, the fundamental basis of these abnormalities at a molecular level is still obscure. One of the key developmental process affected by maternal TH insufficiency is the delay in astrocyte maturation.

Blood pressure (BP) has a characteristic and reproducible circadian pattern, with high values during the day and low values at night. A 7-day timed analysis of BP through ambulatory blood pressure monitoring has been used not only to diagnose day and night dipping patterns of blood pressure, but also to measure day-to-day variability and the circadian hyper-amplitude-tension, a condition in which excessive circadian BP amplitude precedes the chronic established hypertension.
