Ableism, akin to other forms of discrimination such as sexism and racism, is increasingly recognized as a pervasive societal concern directed towards individuals with disabilities. This scholarly inquiry delineates the operational definition, manifestations, and ramifications of ableism, with a specific focus on its manifestations within healthcare settings. It underscores the critical need for targeted interventions aimed at mitigating biases among healthcare professionals and promoting inclusivity within healthcare delivery systems.

The PD-1/PDL-1 immune checkpoint inhibitors revolutionized cancer treatment, yet osteosarcoma remains a therapeutic challenge. In some types of cancer, PD-1 receptor is not solely expressed by immune cells but also by cancer cells, acting either as a tumor suppressor or promoter. While well-characterized in immune cells, little is known about the role and interactome of the PD-1 pathway in cancer.

Article Synopsis
  • The human oral and nasal microbiota consists of around 770 cultivable bacterial species, with over 2,000 genome sequences available in the expanded Human Oral Microbiome Database (eHOMD).
  • Researchers created a Python tool called HOMDscrape to help retrieve and analyze data regarding bacterial motility from eHOMD.
  • The study focused on the evolutionary relationships of motile bacteria, specifically examining the type 9 secretion system (T9SS) and its role in bacterial motility, which may influence how these bacteria coexist in the human oral microbiota.

Cauliflower is an important winter crop grown in India, its curds are rich in nutritional profile, containing valuable minerals and vitamins. However, cauliflower harvesting is mainly accomplished by hands, which is time-consuming and requires a high labour force. On the other hand, most developed cauliflower harvesters are once over or single pass type, which harvests all plants irrespective of their maturity.

Circadian rhythms send messages to regulate the sleep-wake cycle in living beings, which, regulate various biological activities. It is well known that altered sleep-wake cycles affect host metabolism and significantly deregulate the host immunity. The dysregulation of circadian-related genes is critical for various malignancies.

We present the case of a patient with a vestibular schwannoma (VS) who developed vascular complications following surgery and discuss the potential mechanisms. Additionally, we systematically searched the literature to identify citations on vascular and brain stem complications following VS surgery. We excluded the articles related to facial and vestibulocochlear nerve-related complications and other complications, such as headache, tinnitus, and ataxia.

Background and aim In India, socioeconomic factors, healthcare access, and cultural views influence HIV epidemiology. With over two million cases, high-risk groups include drivers, sex workers, and intravenous drug users. Early symptoms often go unnoticed, and advanced stages lead to opportunistic infections.

Article Synopsis
  • Residual blood specimens offer a cost-effective way to track seroprevalence changes compared to traditional household surveys, as shown in a study in India focused on measles-rubella vaccinations.
  • A cross-sectional survey in Kanpur Nagar and Palghar found significant increases in rubella seroprevalence post-immunization, though measles trends were inconsistent between facility and community samples.
  • Younger children in public facilities initially had lower rubella seroprevalence than those in private hospitals, but this gap disappeared after the vaccination campaign, highlighting the importance of residual specimens for public health monitoring.

Article Synopsis
  • The Uninostril Endonasal Transsphenoidal approach preserves nasal anatomy, allowing for normal breathing and fewer nasal complications post-surgery, while providing simplified access and preserving the other nostril for potential use.
  • It is particularly suitable for certain types of pituitary adenomas and focuses on proper patient positioning to facilitate optimal tumor removal and minimize bleeding.
  • However, this technique does face challenges like a limited field of view and potential difficulties in instrument maneuverability, which may necessitate converting to the Bi-nostril approach if complications arise.

The International Molecular Exchange Consortium (IMEx) has evolved into a vital partnership of open resources dedicated to curating molecular interaction data from the scientific literature. This consortium, which includes IntAct, MINT, MatrixDB, and DIP, is a collaborative effort with a central mission of aggregating detailed molecular interaction experimental evidence in a machine-readable format, supported by controlled vocabularies and standard ontologies. The IntAct molecular interaction database (www.

Article Synopsis
  • Many bacteria use the type 9 secretion system (T9SS) for both moving smoothly (gliding motility) and for secreting proteins.
  • The T9SS acts like a rotating motor powered by proton motive force, acting as a "molecular snowmobile" to facilitate movement along the bacterial membrane.
  • A recent discovery shows that altering a specific part of the conveyor belt protein can switch the rotation of T9SS from counterclockwise to clockwise, revealing a mechanism that allows the conveyor belt to influence the motion and direction of the T9SS.

The bacterial Type 9 Secretion System (T9SS) is essential for the development of periodontal diseases and Bacteroidetes gliding motility. T9SS-driven motile bacteria, abundant within the human oral microbiota, transport non-motile oral microbes and bacteriophages as cargo, shaping the spatial structure of polymicrobial communities. However, the physical rules governing the dispersal of T9SS-driven bacterial swarms are barely understood.

Article Synopsis
  • Ng (Neisseria gonorrhoeae) is a major cause of gonorrhea, infecting 87 million people yearly and showing increasing drug resistance, while Nm (Neisseria meningitidis), common in the oropharynx, can lead to bacterial meningitis with about 1.2 million cases globally.*
  • Both pathogens can occupy the same anatomical spaces, allowing for potential horizontal gene transfer (HGT), complicating their detection and treatment.*
  • A study in Milwaukee found isolates that were initially misidentified as Nm but were confirmed as Ng through whole-genome sequencing, showing evidence of HGT from Nm that affected a gene used in differentiating the two species.*

Objective: Triple negative breast cancer (TNBC) is an aggressive from of breast cancer and is associated with poor prognosis. Tumor microenvironment of breast cancer consists of a wide   range of cell types, including tumor-infiltrating lymphocytes (TILs). Accumulating evidence indicate that TILs play a crucial role in cancer progression and resistance to standard chemotherapy.

Background and objective Serum ferritin concentration and transferrin saturation are commonly employed to estimate body iron but are non-specific to iron overload. Glycosylated ferritin may be primarily elevated in cases of iron overload in patients undergoing regular blood transfusions. In this study, we aimed to estimate glycosylated ferritin and determine its cutoff values for iron overload in patients receiving blood transfusions regularly.

Introduction: Bladder cancer disproportionately affects men and often presents as nonmuscle-invasive bladder cancer (NMIBC). Despite initial treatments, the recurrence and progression of NMIBC are linked to autophagy. This study investigates the expression of autophagy genes (mTOR, ULK1, Beclin1, and LC3) in low and high-grade NMIBC, providing insights into potential prognostic markers and therapeutic targets.

Background: Non-eruptive calcium nodules (CNs) are commonly seen in heavily calcified coronary artery disease. They are the most difficult subset for modification, and may result in stent damage, malapposition and under-expansion. There are only limited options available for non-eruptive CN modification.

Electrophysiology typically deals with the electrical properties of excitable cells like neurons and muscles. However, all other cells (non-excitable) also possess bioelectric membrane potentials for intracellular and extracellular communications. These membrane potentials are generated by different ions present in fluids available in and outside the cell, playing a vital role in communication and coordination between the cell and its organelles.
