Impact of AI on the Cyber Kill Chain: A Systematic Review.

The Cyber Kill Chain (CKC) defense model aims to assist subject matter experts in planning, identifying, and executing against cyber intrusion activity, by outlining seven stages required for adversaries to execute an attack. Recent advancements in Artificial Intelligence (AI) have empowered adversaries to execute sophisticated attacks to exploit system vulnerabilities. As a result, it is essential to consider how AI-based tools change the cyber threat landscape and affect the current standard CKC model.

Trends in the Management and Outcomes of Neuroendocrine Liver Metastases: A Three-decade, Multi-centre Observational Cohort Study.

Objective: To describe the evolution of management strategies for neuroendocrine liver metastases (NE LM) and trends in patient outcomes over the preceding 3 decades.

Summary Background Data: Liver metastases are common in neuroendocrine neoplasms and impair prognosis. A broad therapeutic armamentarium has evolved over recent decades but there remains uncertainty regarding optimal treatment selection and sequencing.

Impact of the COVID-19 pandemic on sexually transmitted infection testing and diagnosis in Lebanon: A retrospective chart review.

Background: Social distancing restrictions during the COVID-19 pandemic caused disruptions to sexual health services (SHS) worldwide. During the first year of the pandemic, Lebanon implemented multiple lockdowns during which SHS endured repetitive closures. We explore the impact of the pandemic on SHS delivery and the diagnosis rate of sexually transmitted infections (STIs) among attendees of a large sexual health clinic in Beirut, Lebanon.

Molecular connectomics reveals a glucagon-like peptide 1-sensitive neural circuit for satiety.

Liraglutide and other glucagon-like peptide 1 receptor agonists (GLP-1RAs) are effective weight loss drugs, but how they suppress appetite remains unclear. One potential mechanism is by activating neurons that inhibit the hunger-promoting Agouti-related peptide (AgRP) neurons of the arcuate hypothalamus (Arc). To identify these afferents, we developed a method combining rabies-based connectomics with single-nucleus transcriptomics.

Implementation and validation of single-cell genomics experiments in neuroscience.

Single-cell or single-nucleus transcriptomics is a powerful tool for identifying cell types and cell states. However, hypotheses derived from these assays, including gene expression information, require validation, and their functional relevance needs to be established. The choice of validation depends on numerous factors.

Opportunities and challenges of single-cell and spatially resolved genomics methods for neuroscience discovery.

Over the past decade, single-cell genomics technologies have allowed scalable profiling of cell-type-specific features, which has substantially increased our ability to study cellular diversity and transcriptional programs in heterogeneous tissues. Yet our understanding of mechanisms of gene regulation or the rules that govern interactions between cell types is still limited. The advent of new computational pipelines and technologies, such as single-cell epigenomics and spatially resolved transcriptomics, has created opportunities to explore two new axes of biological variation: cell-intrinsic regulation of cell states and expression programs and interactions between cells.

Investigating the stability of a cerebral vasodilator drug using chromatographic methods: Evaluation of methods' practicality and environmental aspects.

A vinca alkaloid; vinburnine (VNB) is utilized as an effective vasodilator. As a cyclic amide-containing drug, it is likely susceptible to hydrolytic degradation. This study examined the degradation profile of VNB, findings indicated that VNB undergoes degradation solely in the presence of alkali, generating a carboxylic acid derivative (DEG).

Mycophenolate Mofetil-Induced Lymphoproliferative Disorder in a Young Adult With Chronic Posterior Uveitis.

To present a case of a young adult with bilateral chronic posterior uveitis resulting from Vogt-Koyanagi-Harada (VKH) disease treated with mycophenolate mofetil who subsequently developed vitreoretinal lymphoma in the right eye. A case and its findings were analyzed. A 34-year-old Hispanic woman presented with an 8-year history of chronic recurrent posterior uveitis in both eyes secondary to VKH disease.

A cross-disease resource of living human microglia identifies disease-enriched subsets and tool compounds recapitulating microglial states.

Human microglia play a pivotal role in neurological diseases, but we still have an incomplete understanding of microglial heterogeneity, which limits the development of targeted therapies directly modulating their state or function. Here, we use single-cell RNA sequencing to profile 215,680 live human microglia from 74 donors across diverse neurological diseases and CNS regions. We observe a central divide between oxidative and heterocyclic metabolism and identify microglial subsets associated with antigen presentation, motility and proliferation.

A rare case of alirocumab (PCSK9 inhibitor)-associated acute interstitial nephritis.

Acute interstitial nephritis (AIN) is a common cause of hospital-acquired acute kidney injury (AKI) [1]. The most common cause of AIN is drug-induced AIN, which accounts for 60 - 70% of cases [2]. Alirocumab, a proprotein convertase subtilisin/kexin type 9 inhibitor (PCSK9 inhibitor) is a monoclonal antibody that lowers low-density lipoprotein-C levels by inhibiting the PCSK9 protein [3].

The complete mitochondrial genome data of (L.) Skeels.

(L.) Skeels, an endemic Moroccan plant species from the Sapotaceae family, holds significant ecological, pharmaceutical, and socioeconomic value in the arid mid-western region. However, it is facing rapid degradation.

In silico analysis of aptamer-RNA conjugate interactions with human transferrin receptor.

The human transmembrane protein Transferrin Receptor-1 is regarded as a promising target for the systemic delivery of therapeutic agents, particularly of nucleic acid therapeutics, such as short double stranded RNAs. This ubiquitous receptor is involved in cellular iron uptake, keeping intracellular homeostasis. It is overexpressed in multiple cancer cell types and is internalized via clathrin-mediated endocytosis.

A novel artificial intelligence model for diagnosing Acanthamoeba keratitis through confocal microscopy.

Purpose: To develop an artificial intelligence (AI) model to diagnose Acanthamoeba keratitis (AK) based on in vivo confocal microscopy (IVCM) images extracted from the Heidelberg Retinal Tomograph 3 (HRT 3).

Methods: This retrospective cohort study utilized HRT 3 IVCM images from patients who had received a culture-confirmed diagnosis of AK between 2013 and 2021 at Massachusetts Eye and Ear. Two cornea specialists independently labeled the images as AK or nonspecific finding (NSF) in a blind manner.

Intersectional analysis of the experiences of women who fail to conceive in low and middle income neighbourhoods of Delhi, India: Findings from a qualitative study.

Background: Experiences of delayed conception and infertility have been reported among women. However, the concept of intersectionality is rarely utilised in studies of infertility, and it is particularly uncommon in research from low- and middle- income countries.

Research Question: What are the lived experiences of women with delayed conception in low to -middle income neighbourhoods of Delhi, India?

Methods: This was a qualitative study (n = 35) that recruited women who had failed to conceive after 18 months of regular unprotected sexual intercourse.

Molecular genetics, neuroimaging outcomes, and structural analyses of novel and recurrent variants of WDR62 gene in two consanguineous Pakistani families with autosomal recessive primary microcephaly.

Background: Autosomal recessive primary microcephaly (MCPH) is a rare neurodevelopmental and genetically heterogeneous disorder, characterized by small cranium size (> - 3 SD below mean) and often results in varying degree of intellectual disability. Thirty genes have been identified for the etiology of this disorder due to its clinical and genetic heterogeneity.

Methods And Results: Here, we report two consanguineous Pakistani families affected with MCPH exhibiting mutation in WDR62 gene.
