STEM exam performance: Open- versus closed-book methods in the large language model era.

Background: The COVID-19 pandemic accelerated the shift to remote learning, heightening scrutiny of open-book examinations (OBEs) versus closed-book examinations (CBEs) within science, technology, engineering, arts and mathematics (STEM) education. This study evaluates the efficacy of OBEs compared to CBEs on student performance and perceptions within STEM subjects, considering the emerging influence of sophisticated large language models (LLMs) such as GPT-3.

Methods: Adhering to PRISMA guidelines, this systematic review analysed peer-reviewed articles published from 2013, focusing on the impact of OBEs and CBEs on university STEM students.

Cyanide mediated conformational changes resulted in the displacement of sulfate ion from the active site of bovine pancreatic ribonuclease A.

Ribonuclease A is a major hydrolyzing enzyme involved in the hydrolysis of RNA. The crystals of bovine pancreatic RNase A (bpRNase A) were grown at pH 5.5.

Synthesis of isoniazid derivatives and evaluation of their α-chymotrypsin inhibitory effect through in silico guided in vitro studies.

Alpha-chymotrypsin is a serine protease. Its overexpression is responsible for several ailments, such as chronic obstructive pulmonary disease, autoimmune diseases, pancreatitis, and colon cancers. Therefore, the discovery of potent α-chymotrypsin inhibitors is essential for the treatment of the aforementioned ailments.

Structural basis for the binding of famotidine, cimetidine, guanidine, and pimagedine with serine protease.

Serine proteases are among the important groups of enzymes having significant roles in cell biology. Trypsin is a representative member of the serine superfamily of enzymes, produced by acinar cells of pancreas. It is a validated drug target for various ailments including pancreatitis and colorectal cancer.

A Cross-Sectional Study of Cardiovascular Autonomic Reactivity in Ehlers-Danlos Syndrome.

Background: Ehlers-Danlos syndrome (EDS) may be linked to dysfunction in the autonomic nervous system, affecting collagen production and processing. These collagen abnormalities lead to a condition called dysautonomia. Findings underscore the need for further investigation into autonomic nervous system function in EDS which involves larger studies to strengthen the evidence of non-invasive screening tools like cardiovascular reflex tests.

The Latest Evidence on Bempedoic Acid: Meta-Analysis of Safety and Efficacy in High Cardiovascular Risk Patients With Hypercholesterolemia.

Background: Bempedoic Acid (BA) is a novel drug that has a potential to serve as an alternative to statins to decrease lipid levels and improve cardiovascular disease (CVD) outcomes, particularly for statin-intolerant individuals. However, insufficient statistical power has limited our understanding of the efficacy and safety of BA. This meta-analysis utilizes the latest data to improve our knowledge of BA's effects on lipids and CVD with increased statistical power.

In vivo CRISPR screens reveal SCAF1 and USP15 as drivers of pancreatic cancer.

Functionally characterizing the genetic alterations that drive pancreatic cancer is a prerequisite for precision medicine. Here, we perform somatic CRISPR/Cas9 mutagenesis screens to assess the transforming potential of 125 recurrently mutated pancreatic cancer genes, which revealed USP15 and SCAF1 as pancreatic tumor suppressors. Mechanistically, we find that USP15 functions in a haploinsufficient manner and that loss of USP15 or SCAF1 leads to reduced inflammatory TNFα, TGF-β and IL6 responses and increased sensitivity to PARP inhibition and Gemcitabine.

Hypertension Research in Pakistan: A Scientometric Analysis of Two Decades (2003-2022).

Hypertension is a highly prevalent chronic disease that leads to a significant number of deaths and disabilities as a consequence of cardiovascular complications. However, there is insufficient information regarding research trends and performance assessments from South Asian countries, including Pakistan. In this review, we analyzed research data related to hypertension from Pakistan over the last 20 years (2003-2022).

Neurosurgery and Social Media: A Bibliometric Analysis of Scientific Production from 2004 to 2023.

Background: Neurosurgery is a rapidly advancing surgical specialty. Social media has significantly impacted the landscape of advancements in the field of neurosurgery. Research on the subject of neurosurgery and social media plays a vital role in combating disability and mortality due to neurological diseases, especially in trauma-affected individuals by increasing cooperation and sharing of clinical experiences between neurosurgeons via social media.

Identification, crystallization, and first X-ray structure analyses of phenyl boronic acid-based inhibitors of human carbonic anhydrase-II.

Human carbonic anhydrases (hCAs) play a central role in various physiological processes in the human body. HCAs catalyze the reversible hydration of CO into HCO, and hence maintains the fluid and pH balance. Overexpression of CA II is associated with diseases, such as glaucoma, and epilepsy.

A Cotton Rope in the Colon: A Rare Cause of Chronic Abdominal Pain.

Retained surgical sponge is a relatively rare medical condition with potential serious medicolegal implications. The term "gossypiboma" is frequently used to describe this condition. We present a case of a 40-cm-long retained surgical sponge in a 43-year-old woman who presented with unexplained chronic abdominal pain for several years.

Efficient Thorax Disease Classification and Localization Using DCNN and Chest X-ray Images.

Thorax disease is a life-threatening disease caused by bacterial infections that occur in the lungs. It could be deadly if not treated at the right time, so early diagnosis of thoracic diseases is vital. The suggested study can assist radiologists in more swiftly diagnosing thorax disorders and in the rapid airport screening of patients with a thorax disease, such as pneumonia.
