Article Synopsis
  • Primary pulmonary lymphoma (PPL) is a rare lung condition where lymphoid cells grow abnormally, leading to symptoms like cough, fever, and shortness of breath; it can often be misdiagnosed as tuberculosis due to overlapping symptoms.
  • Accurate diagnosis of PPL is critical and typically requires small biopsies for histopathological analysis, guiding treatment options such as chemotherapy and immunotherapy.
  • The text presents a case of a patient initially thought to have tuberculosis but diagnosed with PPL through thorough evaluations, including a thoracoscopy-guided biopsy, emphasizing the importance of a multidisciplinary approach for effective diagnosis and management.

Background: In graph theory, M polynomials like the matching polynomial are very crucial in examining the matching structures within graphs, while NM polynomials extends this to analyze non-matching edges. These polynomials are important in many fields, including chemistry and network architecture. They support the derivation of topological indices for protein structure analysis, network communication optimization, and drug design in QSAR/QSPR investigations.

Inappropriate antibiotic use not only amplifies the threat of antimicrobial resistance (AMR), moreover exacerbates the spread of resistant bacterial strains and genes in the environment, underscoring the critical need for effective research and interventions. Our aim is to assess the prevalence and resistance characteristics of β-lactam resistant bacteria (BLRB) and β-lactamase resistant bacterial genes (BLRBGs) under various environmental conditions within Delhi NCR, India. Using a culture-dependent method, we isolated 130 BLRB from 75 different environmental samples, including lakes, ponds, the Yamuna River, agricultural soil, aquatic weeds, drains, dumping yards, STPs, and gaushalas.

Synovial lipomatosis or lipoma arborescens is a very uncommon pseudo-tumorous lesion of the synovium which more commonly affects the knee joint. The most probable cause of this pathological lesion is degenerative articular disorders of the joint and improper fat accumulation. It is characterized by presence of villous proliferation of the synovium and replacement of the sub-synovial tissue by mature adipocytes which is infiltrated by dense chronic inflammatory cells like lymphocytes, plasma cells and eosinophils.

Herein, we report palladium supported on a hydroxyapatite catalyst for synthesizing tri-substituted pyridines using ammonium acetate as the nitrogen source acceptorless alcohol dehydrogenation strategy. The strategy offers a broad substrate scope using inexpensive and readily available alcohols as the starting material. The catalyst was prepared using a simple method and analyzed by several techniques, including FE-SEM, EDS, HR-TEM, BET, XRD, FT-IR, UV-visible spectroscopy, and XPS, demonstrating the anchoring of Pd nanoparticles on hydroxyapatite in the zero oxidation state.

Early disease detection is often correlated with a reduction in mortality rate and improved prognosis. Currently, techniques like biopsy and imaging that are used to screen chronic diseases are invasive, costly or inaccessible to a large population. Thus, a non-invasive disease screening technology is the need of the hour.

Paddy straw (PS) burning is a concerning issue in South Asian countries, clamoring for exploring alternative management strategies. Being a rich source of silica, PS can be a potential nanosilica (SiNPs) source. The current study reports a pioneering approach for green synthesis of high-purity mesoporous SiNPs by sol-gel method using the aqueous extract of Sapindus mukorossi seed pericarp as a stabilizer.

Petersdorf and Beeson first defined fever of unknown origin (FUO) in 1961, and subsequently, over the next 60 years, the definition of FUO has changed considerably. In the western world, non-infectious inflammatory diseases are the most common cause of FUO; however, in developing countries, infections remain the leading cause of FUO. Dermatomyositis (DM) is an autoimmune inflammatory disease of unknown aetiology which mainly affects skin and muscles.

β-lactams are large group of antibiotics widely used to suppress the bacterial growth by inhibiting cell wall synthesis. Bacterial resistance against β-lactam antibiotics is primarily mediated through the production of Temoneria (TEM) β-lactamase (BLs), with almost 474 variants identified in Lactamase Engineering Database (LacED). The present study aims to develop a model to track the evolution of TEM BLs and their interactions with β-lactam and BLs inhibitors through data mining and computational approaches.

Background: Accurately distinguishing the severity of pathophysiology from the level of symptom intensity and incapability is a foundation of effective treatment strategies under the biopsychosocial paradigm of illness. With respect to idiopathic median neuropathy at the carpal tunnel (the symptoms and signs of which are referred to as carpal tunnel syndrome), surgeons who are more likely to recommend surgery based on the magnitude of symptoms and incapability rather than the severity of neuropathy may be underappreciating and undertreating mental health opportunities and overtreating mild, and on occasion unmeasurable, disease. A survey-based experiment that randomizes elements of the patient presentation can help determine the relative influence of magnitude of incapability on ratings of pathology severity.

Article Synopsis
  • - The study investigates D-dimer levels in COVID-19 patients, comparing those with diabetes to those without, given that diabetes is linked to worse outcomes in severe COVID-19 cases.
  • - A total of 98 patients were analyzed, revealing that those with diabetes had significantly higher peak D-dimer levels (1509 ng/mL) compared to non-diabetic patients (515 ng/mL).
  • - The findings suggest that COVID-19 patients with diabetes may face a greater risk of hypercoagulability and poorer prognosis, but further research is needed to understand the clinical implications of these results.
