Purpose: Sarcopenic obesity, characterized by increased adiposity with low skeletal muscle mass, contributes to frailty and the development of chronic disease. Data on sarcopenic obesity in survivors of childhood acute lymphoblastic leukemia (cALL) is limited.

Methodology: A cross-sectional study on 65 cALL survivors (7-18 years, > 2 years from treatment completion) was conducted on cALL survivors with the primary outcome to determine the prevalence of sarcopenic obesity.

Introduction: Preeclampsia (PE) arises due to defective spiral artery remodelling which may be due to deficient migration of trophoblast cells. Migration of human endothelial cells has been shown to be promoted via Hydrogen sulphide(HS)/Rho GTPase Rac1 axis. This novel role of HS and its downstream processes have not yet been studied in the development and function of the placental trophoblast cells.

Introduction: Two pharmacological possibilities exist for an acute ischemic stroke (AIS): recanalization of the occluded artery and neuroprotection from ischaemic injury, the latter's efficacy being debatable. We sought to determine whether administration of Citicoline immediately after recanalization therapy for AIS would improve clinical and radiological outcome at three months compared to standard treatment alone.

Patients And Methods: CAISR was a single centre, randomized, placebo-controlled, parallel-group trial with blinded endpoint assessment.

Alzheimer's disease (AD) is an accelerating neurodegenerative disorder. Dysfunction of mitochondria and oxidative stress contributes to the pathogenesis of AD. Sirtuins play a role in this pathway and can be a potential marker to study neurodegenerative changes.

Background: Alzheimer's disease (AD) is the progressive brain disorder which degenerates brain cells connection and causes memory loss. Although AD is irreversible, it is not impossible to arrest or slow down the progression of the disease. However, this would only be possible if the disease is diagnosed at an early stage, and early diagnosis requires clear understanding of the pathogenesis at molecular level.

Article Synopsis
  • Cancer poses significant challenges for older adults, especially in developing countries where resources are limited, necessitating improved care strategies.
  • A study with 419 older cancer patients (average age 66.6) showed high rates of functional impairment (75%), malnutrition (35%), and co-morbidities (64%), revealing a median survival time of 22 weeks.
  • The newly developed SCOPE-C screening tool effectively predicted survival outcomes, with a score of 64 indicating a good prognosis, highlighting its potential to enhance treatment decisions in constrained healthcare environments.

Background: Metabolic patterns on brain F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) can predict the decline in amnestic mild cognitive impairment (aMCI) to Alzheimer's disease dementia (AD) or other dementias.

Objective: This study was undertaken to evaluate the diagnostic accuracy of baseline F-18 FDG-PET in aMCI for predicting conversion to AD or other dementias on follow-up.

Patients And Methods: A total of 87 patients with aMCI were enrolled in the study.

Sestrin2 (Sesn2) appears to mediate neuroprotection against Parkinson's disease (PD)-associated pathophysiology, however, the mechanism is unknown. This pilot study examines serum Sesn2 level in PD patients and older adult control and also interrogates the rescue effect of Syzygium aromaticum extract on the neurotoxicity by paraquat in neuroblastoma cells. The blood sample was collected from 36 PD patients and 54 older adult control and concentration of serum Sesn2 was measured by surface plasmon resonance and western blot.

Atypical Parkinson syndromes (APSs) often have symptoms that overlap with those of Parkinson's disease (PD), especially early in the disease, making these disorders difficult to diagnose. Previous studies have demonstrated an association of oligomeric α-synuclein (α-Syn), a key element in the pathogenesis of PD, with Sirtuin (SIRT)2 proteins for modulating PD. We aimed to evaluate SIRT protein expression in serum of PD patients and compare it with APSs and normal elderly control (GC) and to correlate this with α-Syn.

Frailty in elderly is very much familiar with a decline in the musculoskeletal system. Muscle degeneration in the lower organism was observed due to loss of anti-oxidant protein Sestrin. The aim of the study is to determine the level of Sestrin1 and Sestrin2 in the serum of frail and non-frail elderly to associate their impact in frailty syndrome.

Background: Cyclin dependent kinase inhibitor 2A/B (CDKN2A/B) genes are implicated in many malignancies including acute lymphoblastic leukemia (ALL). These tumor suppressor genes, with a key regulatory role in cell cycle are located on chromosome 9p21.3.

Background: Polymorphism of NFKB1 and NFKB1A are highly associated with cancer. We have assessed polymorphism in the promoter region of NFKB1 -94 del/ins ATTG (rs28362491) and NFKB1A -826 C/T (rs2233406) with the risk of HNSCC in Indian population. Methods: Polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP) method was used for the genotyping NFKB1 -94 del/ins ATTG and NFKB1A -826 C/T.

Human leukocyte antigen (HLA-G) is a potent immune-tolerant molecule and has a critical role in various pathological conditions of cancer. The aim of the study was to analyze the association of HLA-G polymorphism as a risk factor in Head and Neck Squamous Cell Carcinoma (HNSCC). The HLA-G polymorphism at 3'UTR 14bp INDEL (rs371194629) and +3142G/C (rs1063320) were studied in 383 HNSCC patients and 383 ethnically similar-aged healthy controls in North Indian population.

Sestrins (sesn) are highly conserved proteins that play an important neuroprotective role, in part as a consequence of their antioxidative capacity, which prevents reactive oxygen species formation. In this study, we evaluated the concentrations of sesn1 and sesn2 in the serum of 41 Alzheimer's disease (AD) patients, 27 mild cognitive impairment (MCI), and 60 elderly controls, by surface plasmon resonance, which was validated by using western blot. Moreover, the mRNA level of sestrins in all the study groups was determined by real time polymerase chain reaction.

The elevated level of cerebrospinal fluid (CSF) Tau and phosphorylated Tau181 (p-Tau181) proteins are well established hallmarks of Alzheimer's disease (AD). Elevated level of p-Tau181 can differentiate AD from other neurodegenerative disease. However, the expression level of these proteins in serum of AD patient is not well set up.

Objective: Radioiodine, in low doses, has been used as a treatment modality for hyperthyroidism worldwide for a long time. However, there is little information available on the severity of cytotoxicity of radioiodine at these low doses. The present investigation aimed to study the cytogenetic toxicity of low-dose radioiodine in hyperthyroid patients using a cytokinesis-blocked micronuclei (MN) assay.

Most patients with gall bladder cancer (GBC) present in the advanced stage with a poor response to therapy. Prevention or early detection is the best way to prevent death, but this requires identification of susceptible subgroups. Keeping this in mind, this study was carried out to evaluate the association between selected demographic, lifestyle, and dietary factors and GBC.
