Background: Acute cholecystitis (AC) is increasingly common and imposes a burden on healthcare systems, particularly in the elderly population. While laparoscopic cholecystectomy (LC) is the definitive treatment, percutaneous cholecystostomy (PC) is often preferred based on various factors. The treatment of elderly patients requires a multidisciplinary approach that carefully assesses surgical risks due to age-related changes and comorbidities.

The advent of spatial transcriptomics and spatial proteomics have enabled profound insights into tissue organization to provide systems-level understanding of diseases. Both technologies currently remain largely independent, and emerging same slide spatial multi-omics approaches are generally limited in plex, spatial resolution, and analytical approaches. We introduce IN-situ DEtailed Phenotyping To High-resolution transcriptomics (IN-DEPTH), a streamlined and resource-effective approach compatible with various spatial platforms.

Humans navigate diverse social relationships and concurrently interact across multiple social contexts. An individual's behavior in one context can influence behavior in other contexts. Different payoffs associated with interactions in the different domains have motivated recent studies of the evolution of cooperation through the analysis of multichannel games where each individual is simultaneously engaged in multiple repeated games.

Article Synopsis
  • - The study focused on noise-induced hearing loss among power loom workers in Tamil Nadu, India, aiming to assess noise exposure levels and determine the prevalence of hearing loss among workers.
  • - A total of 123 workers were surveyed, revealing that 88.5% were exposed to noise levels of ≥ 95 dB (A), with a hearing loss prevalence of 71.6%. Important factors linked to hearing loss included age, literacy level, and years of service in the industry.
  • - To address these issues, the study recommends improved education on occupational hazards, stricter safety regulations, regular hearing tests, and the implementation of hearing conservation programs in noisy workplaces.

Enyne diesters derived from 2-propargyloxyarylaldehydes are converted into 2-oxopyranochromenes via In(OTf)-catalyzed cycloisomerization and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ)-mediated oxidative cyclization reaction sequence in one pot. The process possesses broad substrate scope and good functional group compatibility and generates various 4-(hetero)aryl-substituted 2-oxopyranochromenes in 32-79% yields (over two steps). 2-Oxopyranochromenes undergo selective decarboxylation under Krapcho conditions.

  • Repeat expansions in the C9orf72 gene are a leading genetic cause of ALS and frontotemporal dementia, but understanding how this mutation causes neuron death is still unclear, complicating the search for effective therapies.
  • Researchers analyzed data from over 41,000 ALS and healthy samples to identify potential treatments, discovering that acamprosate, a drug used for other conditions, might be repurposed for C9orf72-related diseases.
  • Their findings demonstrated that acamprosate has neuroprotective properties in cell models and works similarly well as the current treatment, riluzole, showing the potential of using genomic data to find new drug applications.

One of the most prevalent cancers globally is breast cancer and approximately two thirds of the breast cancers are hormone receptor positive with estrogen receptors (ER) being a prominent target. Notably, p53 that controls several cellular functions and prevents tumor formation, gets suppressed in breast cancers. Reactivation of p53 can lead to cell cycle arrest as well as apoptosis.

Background: Cerebellar ataxia, neuropathy and vestibular areflexia syndrome (CANVAS), a relatively common cause of late-onset progressive ataxia, is a genetic disease characterised by biallelic pentanucleotide AAGGG repeat expansion in intron 2 of the replication factor complex subunit 1 gene. Herein, we describe the first molecularly confirmed CANVAS family with five affected siblings from Turkey.

Case Presentation: The family comprised seven siblings born from healthy non-consanguineous parents.

Article Synopsis
  • This study investigates the effects of extensive surgical resection on outcomes for patients with wild-type IDH glioblastoma, considering the influence of genetic mutations like TERT and EGFR.
  • The analysis included 41 out of 723 patients who underwent either partial or extensive surgeries from 2014 to 2022, focusing on tumor recurrence-free periods and overall survival rates.
  • Results showed that extensive resection led to longer tumor-free intervals and better quality of life scores, although it did not significantly improve overall survival rates despite the presence of TERT mutations and EGFR amplification.

Background: Autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) is a common recessive ataxia that is still underdiagnosed worldwide. An easily accessible diagnostic biomarker might help to diagnostically confirm patients presenting SACS variants of unknown significance (VUS) or atypical phenotypes.

Objectives: To detect sacsin in peripheral blood mononuclear cells (PBMCs) and to validate its diagnostic biomarker quality to discriminate biallelic SACS patients (including patients with VUS and/or atypical phenotypes) against healthy controls, non-ARSACS spastic ataxia patients, and heterozygous SACS carriers.

Baby corn, characterized by its high water activity and elevated respiration rate, poses a formidable obstacle to prolonged storage under standard ambient conditions and necessitates specialized treatments for transportation to distant locations. One of the primary postharvest challenges associated with baby corn is the occurrence of brown pigment formation because of enzymatic browning at the apex of its immature ovules, cut surfaces, and silk attached to the young ears. The present study was undertaken to investigate the effect of different blanching treatments on peroxidase inactivation, physicochemical properties, and functional properties of baby corn.

  • Cancer vaccine development is challenged by the need for effective strategies to enhance dendritic cell (DC) induction of tumor-specific immunity, particularly through T cell function.
  • A novel glycan-costumed virus-like particle (VLP) vaccine was created, featuring a DC-SIGN-selective ligand and TLR7 agonists, which boosts DC activation and type 1 cellular immunity.
  • In mouse studies, this VLP vaccine successfully generated tumor-specific T cells, leading to significant tumor growth inhibition, highlighting its potential for improving cancer immunotherapies.

  • Climate change and human activities significantly disrupt natural ecosystems, leading to critical transitions where ecosystems can abruptly shift to alternative stable states.
  • This study focuses on how rapid environmental changes, particularly in the spruce budworm model, can trigger such tipping phenomena based on the strength and duration of environmental pulses.
  • The research reveals that even a slower subsequent environmental pulse can cause tipping by interacting with ecological timescales and the movement of basin boundaries, highlighting complex dynamics in ecosystem responses to environmental changes.

Periodic environmental variability is a common source affecting ecosystems and regulating their dynamics. This paper investigates the effects of periodic variation in species growth rate on the population dynamics of three bistable ecological systems. The first is a one-dimensional insect population model with coexisting outbreak and refuge equilibrium states, the second one describes two-species predator-prey interactions with extinction and coexistence states, and the third one is a three-species food chain model where chaotic and limit cycle states may coexist.

Background: High-energy casualties such as firearm injuries may result in extensive loss of soft tissue and bone in the lower extremities. Although the primary aim in these types of injuries is the preservation of the extremity, repeated surgical procedures for extremity salvage and subsequent restoration of function could have detrimental effects on the patient both physically and psychologically. The main aim of this study is to evaluate the physical and psychological outcomes of patients who underwent lower extremity amputation in the early period after a firearm injury compared with the results of patients who underwent amputation in the late period.
