Solid pseudopapillary neoplasms (SPNs) of the pancreas are rare tumours with distinctive clinicopathological features. We present a case of a 51-year-old female with a large cystic neoplasm involving the entire pancreas, initially presenting with abdominal pain. Diagnostic imaging revealed a well-defined heterogeneously enhancing mixed solid cystic lesion in the pancreas.

The human gut microbiome plays a vital role in preserving individual health and is intricately involved in essential functions. Imbalances or dysbiosis within the microbiome can significantly impact human health and are associated with many diseases. Several metaproteomics platforms are currently available to study microbial proteins within complex microbial communities.

Post COVID-19, there has been renewed interest in understanding the pathogens challenging the human health and evaluate our preparedness towards dealing with health challenges in future. In this endeavour, it is not only the bacteria and the viruses, but a greater community of pathogens. Such pathogenic microorganisms, include protozoa, fungi and worms, which establish a distinct variety of disease-causing agents with the capability to impact the host's well-being as well as the equity of ecosystem.

Article Synopsis
  • Endoscopic screening for esophageal cancer (EC) can enhance early diagnosis, but current optical microendoscopic methods struggle with limited field of view, impacting efficiency.
  • This study introduces a new end-expandable optical fiber probe aimed at improving the visual field and utilizes a deep-learning-based image super-resolution (DL-SR) method to enhance image quality.
  • Results show that the DL-SR method significantly improves image quality and allows endoscopists to interpret super-resolved images similarly to high-resolution ones, potentially advancing EC screening practices.

Unlabelled: Unravelling genetic networks regulating developmental programs are key to devising and implementing genomics assisted trait modification strategies. It is crucial to understand the role of small RNAs, and the basis of their ability to modify traits. MIR159 has been previously reported to cause defects in anther development in ; however, the complete spectrum and basis of the defects remained unclear.

Article Synopsis
  • - Cronkhite-Canada Syndrome (CCS) is a rare polyposis condition affecting 1 in a million, with unknown causes and treatments due to its scarcity and lack of research models.
  • - Researchers created human intestinal organoids (HIOs) from two CCS patients, finding that these organoids are highly proliferative and produce more serotonin (5HT), which is linked to the growth of intestinal tissue.
  • - The study highlights how organoid cultures can help understand CCS's disease mechanisms and could lead to personalized treatments, demonstrating the impact of intestinal hormones on epithelial cell growth.

Mycobacterial pathogens, including nontuberculous mycobacteria (NTM) and Mycobacterium tuberculosis, are pathogens of significant worldwide interest owing to their inherent drug resistance to a wide variety of FDA-approved drugs as well as causing a broad range of serious infections. Identifying new antibiotics active against mycobacterial pathogens is an urgent unmet need, especially those antibiotics that can bypass existing resistance mechanisms. In this study, we demonstrate that gepotidacin, a first-in-class triazaacenapthylene topoisomerase inhibitor, demonstrates potent activity against M.

Microorganisms in human gastrointestinal tract have profound influence on the transformation of food into metabolites which can impact human health. Along with playing crucial roles in regulating and modulating various metabolic reactions and life processes, dysbiosis of gut microbiota also affects the permeability of gut and blood-brain barrier. This increases the chance of age-related neurological disorders' like Alzheimer's and Parkinson's diseases.

Background: Patients with opioid use disorder (OUD) have a significant problem in psychosocial functioning domains, which are not systematically studied in India. This study aimed to evaluate the psychosocial functioning in current noninjecting opioid users on Methadone Maintenance Treatment (MMT) versus Treatment as Usual (TaU: , , , , , ).

Materials And Methods: It is a cross-sectional study on patients of current noninjecting OUD on MMT or TaU for at least in the past month.

The inability of neural cells to regenerate themselves after an injury represents the major difference between neural cells and other cells of the body. Various factors are responsible for this, as the expression of myelin-derived inhibitors of axonal outgrowth such as neurite outgrowth inhibitor (Nogo), myelin-associated growth factor, and oligodendrocyte-myelin glycoprotein (OMgp) hinder the central nervous system (CNS) axons to recover properly and inhibit the neuron regeneration. The patient with spinal cord injury can even permanently lose their function due to the inability of axons to regenerate.

Introduction: SARS-CoV-2 a new virus of the zoonotic coronavirus family causes the disease COVID-19, which has become a global pandemic. One of the ways for prevention of COVID-19 is by disabling its spike protein which results in inhibiting its binding with angiotensin-converting enzyme 2 (ACE-2). The other alternative is to inhibit its replication once inside the body.

In the year 2019, the potent zoonotic virus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) began to rage globally, which resulted in the World Health Organization (WHO) declaring it as a pandemic on March 11th, 2020. Although extensive research is currently ongoing worldwide to understand the molecular mechanism and disease pathogenicity of SARS-CoV-2, there are still many nuances to elucidate. Therefore, developing an appropriate vaccine or therapeutic drug to combat coronavirus 2019 (COVID-19) is exceedingly challenging.

Background: The risk and determinants of HCC in patients with primary biliary cholangitis (PBC) are unclear. We conducted a systematic review and meta-analysis of the incidence of HCC and risk factors associated with HCC risk among patients with PBC.

Methods: We searched PubMed, EMBASE, MEDLINE, Cochrane databases and reference lists from relevant articles to identify cohort studies that examined incidence of HCC in patients with PBC from inception through November 2019.

An uncommon deadly genetic situation symbolized by the presence of rapid maturation in infants is called as the Hutchinson-Gilford Progeria Syndrome. The term basically is meant as 'prematurely old' taken from the Greek meanings. The selective cause behind this syndrome is usually a mutation in a gene called LMNA.

Background: Clinically, melatonin (MLT) has variable oral absorption and extensive first-pass effect, making its oral mode less preferable. Ethosomes are able to permeate intact through the human skin due to its high deformability.

Aim: Present study assessed topical potential of ethosomes loaded with MLT for the prevention of UV radiation.

Purpose: This phase II study evaluated the utility of magnetic resonance imaging (MRI) and positron emission tomography for planning radiation and brachytherapy in patients with postsurgical recurrence of cervical cancer.

Methods And Materials: The study (NCT01391065) recruited patients with residual or recurrent disease after hysterectomy. Patients underwent baseline T2 weighted (T2W) MRI, F-flouro-deoxyglucose (F-FDG), F-flouro thymidine (F-FLT) and F-flouromisonidazole (F-F Miso) positron emission tomography (PET) and received external radiation (50 Gy/25 fractions for 5 weeks) and weekly cisplatin (40 mg/m).
