Background People with visual impairment (VI) tend to face more psychological distress than normally sighted individuals due to mobility restrictions, fear of falling, and sleep disturbances. However, research to address these problems is rare. This study aims to investigate the effect of mindfulness-based yoga versus physical exercise on the psychological well-being of individuals with VI.

Introduction: Sickle cell disease (SCD) is a genetic blood disorder that affects the shape and function of red blood cells (RBCs), which can lead to several health problems affecting the quality of life. SCD can be treated with certain expensive treatments such as RBC transfusion, hydroxyurea, stem cell transplantation, gene therapy, or bone marrow transplant. However, some of the most common symptoms such as pain, anxiety, and stress can also be alleviated with alternative therapies like yoga.

Introduction: The conceptualisation of healthy ageing phenotype (HAP) and the availability of a tentative panel for HAP biomarkers raise the need to test the efficacy of potential interventions to promote health in older adults. This study protocol reports the methodology for a 24-week programme to explore the holistic influence of the yoga-based intervention on the (bio)markers of HAP.

Methods And Analysis: The study is a two-armed, randomised waitlist controlled trial with blinded outcome assessors and multiple primary outcomes.

Background: Although yoga is found to be beneficial in the management of type 2 diabetes (T2D), its mechanism of action is poorly understood. T2D is also known to be associated with increased oxidative stress (OS) and DNA damage.

Purpose: This study examines how yoga modulates OS-induced DNA damage and the efficiency of DNA repair in T2D conditions.

Objectives: The objective of the study is to evaluate the short-term effect of yoga on plasma glucose, lipid profile, blood pressure and insulin requirement in a patient with type 1 diabetes mellitus (T1DM).

Case Presentation: A 28-years old female was diagnosed with T1DM at the age of seven. She was under Human Mixtard insulin 30-70, thrice/day for 15-15-15 units.

Context: HIV/AIDS individuals have problems relating to immune system, quality of life (QOL), and cognitive functions (CFs). Yoga is found to be useful in similar conditions. Hardly, any work is reported on yoga for HIV-positive adults/adolescents.

Background: Yoga is the most popular form of alternative medicine for the management of diabetes mellitus type 2. The electro-photonic imaging (EPI) is another contribution from alternative medicine in health monitoring.

Aim: To evaluate diabetes from EPI perspective.

Background: Type 2 Diabetes Mellitus (T2DM) is turning out to be a global health crisis. Currently available literature clearly indicates an increased risk of type 2 diabetes amongst South Asian population.

Objective: The objective of this narrative review is to explore the non-modifiable and modifiable risk factors of T2DM in South Asian population, including their beliefs, attitudes, socio economic and cultural barriers and also to explore the possible implications in designing culture specific diabetes prevention and management programs.

Introduction: Electrophotonic imaging (EPI), also known as gas discharge visualization, is a technique of capturing images of phenomena not quantifiable by the naked eye. Different sectors at the tip of fingers represent various organs and systems as per the Chinese system of acupuncture. The images from these fingertips can be used to determine the state of health.

The global transcriptional regulator H-NS selectively silences bacterial genes associated with pathogenicity and responses to environmental insults. Although there is ample evidence that H-NS binds preferentially to DNA containing curved regions, we show here that a major basis for this selectivity is the presence of a conserved sequence motif in H-NS target transcriptons. We further show that there is a strong tendency for the H-NS binding sites to be clustered, both within operons and in genes contained in the pathogenicity-associated islands.

Regulation of cellular growth implies spatiotemporally coordinated programmes of gene transcription. A central question, therefore, is how global transcription is coordinated in the genome. The growth of the unicellular organism Escherichia coli is associated with changes in both the global superhelicity modulated by cellular topoisomerase activity and the relative proportions of the abundant DNA-architectural chromatin proteins.

The Escherichia coli DNA architectural protein FIS activates transcription from stable RNA promoters on entry into exponential growth and also reduces the level of negative supercoiling. Here we show that such a reduction decreases the activity of the tyrT promoter but that activation by FIS rescues tyrT transcription at non-optimal superhelical densities. Additionally we show that three different "up" mutations in the tyrT core promoter either abolish or reduce the dependence of tyrT transcription on both high negative superhelicity and FIS in vivo and infer that the specific sequence organisation of the core promoter couples the control of transcription initiation by negative superhelicity and FIS.
