Ultrastructural disturbances in microglia-neuron interactions in the head of the caudate nucleus in schizophrenia.

Eur Arch Psychiatry Clin Neurosci

December 2024

Laboratory of Clinical Neuropathology, Mental Health Research Center, Kashirskoe Shosse 34, 115522, Moscow, Russia.

Previously we found altered microglia-neuron interactions in the prefrontal cortex in schizophrenia. We hypothesized that microglia-neuron interactions may be dysregulated in the caudate nucleus in schizophrenia. A postmortem ultrastructural morphometric study was performed to investigate satellite microglia (SatMg) and adjacent neurons in the head of the caudate nucleus in 21 cases of schizophrenia and 20 healthy controls.

Drug Resist Updat

December 2024

Department of Clinical Laboratory, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, Hangzhou, China; Key Laboratory of Precision Medicine in Diagnosis and Monitoring Research of Zhejiang Province, Hangzhou, China. Electronic address:

To characterize the genomic features of a community-acquired Acinetobacter baumannii strain, co-carrying tet(X6) and bla genes, but was susceptible to tigecycline and carbapenems. The tet(X6) and bla genes were found on a 149,518 bp non-conjugative plasmid. The bla gene was silent, due to the presence of an intact ISAba3-like element upstream, which rendered the strain susceptible to carbapenems.

We report a case of Acanthamoeba infection in an HCT recipient with steroid-refractory GVHD. We highlight the multiple challenges that free-living ameba infections present to the clinician, the clinical laboratory, transplant infectious disease for review, hospital epidemiology if nosocomial transmission is considered, and public health officials, as exposure source identification can be a significant challenge. Transplant physicians should include Acanthamoeba infections in their differential diagnosis of a patient with skin, sinus, lung, and/or brain involvement.

A ganglioside-based immune checkpoint enables senescent cells to evade immunosurveillance during aging.

Nat Aging

December 2024

Université Côte d'Azur, Centre National de la Recherche Scientifique (CNRS) UMR7284, Institut National de la Santé et de la Recherche Médicale (INSERM) U1081, Institute for Research on Cancer and Aging, Nice (IRCAN), Nice, France.

Although senescent cells can be eliminated by the immune system, they tend to accumulate with age in various tissues. Here we show that senescent cells can evade immune clearance by natural killer (NK) cells by upregulating the expression of the disialylated ganglioside GD3 at their surface. The increased level of GD3 expression on senescent cells that naturally occurs upon aging in liver, lung, kidney or bones leads to a strong suppression of NK-cell-mediated immunosurveillance.

Toxins (Basel)

December 2024

Department of Epidemiology and Health Statistics, The Key Laboratory of Typical Environmental Pollution and Health Hazards of Hunan Province, School of Public Health, Hengyang Medical School, University of South China, Hengyang 421001, China.

A growing body of evidence indicates that microcystins (MCs) exposure may cause metabolic diseases. However, studies exploring the effects of MCs exposure on the risk of metabolic syndrome (MetS) in humans are currently lacking, and the underlying mechanisms remain unclear. Here, we conducted a cross-sectional study in central China to explore the effect of serum MCs on MetS, and assessed the mediation effects of the inflammation biomarker, white blood cell (WBC) level, in this relationship.

A Highly Stable Electrochemical Sensor Based on a Metal-Organic Framework/Reduced Graphene Oxide Composite for Monitoring the Ammonium in Sweat.

Biosensors (Basel)

December 2024

Guangdong Laboratory of Artificial Intelligence and Digital Economy (SZ), Shenzhen 518107, China.

The demand for non-invasive, real-time health monitoring has driven advancements in wearable sensors for tracking biomarkers in sweat. Ammonium ions (NH) in sweat serve as indicators of metabolic function, muscle fatigue, and kidney health. Although current ion-selective all-solid-state printed sensors based on nanocomposites typically exhibit good sensitivity (~50 mV/log [NH]), low detection limits (LOD ranging from 10 to 10 M), and wide linearity ranges (from 10 to 10 M), few have reported the stability test results necessary for their integration into commercial products for future practical applications.

Fungal skin infections significantly contribute to the global human disease burden, yet our understanding of cutaneous immunity against dermatophytes remains limited. Previously, we developed a model of epicutaneous infection with Microsporum canis in C57BL/6 mice, which highlighted the critical role of IL-17RA signaling in anti-dermatophyte defenses. Here, we expanded our investigation to the human pathogen Nannizzia gypsea and demonstrated that skin γδTCRint and CD8/CD4 double-negative βTCR+ T cells are the principal producers of IL-17A during dermatophytosis.

Levosimendan is a positive inotrope and vasodilator used in patients with acute and chronic decompensated heart failure. It is metabolized into OR-1855 (inactive metabolite), which is further acetylated into OR-1896 (active metabolite having a prolonged half-life, hence a sustained effect). Levosimendan represents a valuable alternative to traditional inotropes with broad clinical applications in critically ill patients with cardiogenic shock, advanced heart failure and post-cardiac surgery.
