Traditional Bone Setting Leading to Compartment Syndrome of Arm: A Case Report.

INTRODUCTION: The traditional practice of bone setting is more prevalent in developing countries, including India. These traditional practices of fracture management lead to numerous limb-threatening complications like non-union, pressure necrosis, gas gangrene, nerve palsies, necrotizing fasciitis, and most importantly, compartment syndrome. Approximately 75% of acute compartment syndrome (ACS) occurs due to an underlying long bone fracture, most commonly fractures of the tibia, followed by forearm fractures. We report a case of rare occurrence of compartment syndrome of the arm, highlighting…

Unusual colony morphology of Burkholderia pseudomallei leading to initial diagnostic dilemma.

Burkholderia pseudomallei, an environmental Gram-negative saprophyte is the causative agent of melioidosis, a potentially fatal yet treatable clinical entity. We report an unusual colony morphology of the organism to minimize misidentification and enable accurate diagnosis.

Desmoplakin Loss Leads to PKC- and Src-Mediated Contractile Dysfunction in Cardiomyocytes.

BACKGROUND: Mutations in DSP, which encodes the protein desmoplakin, lead to cardiomyopathy with unusually high penetrance that presents with arrhythmias, fibro-fatty infiltration, and eventually heart failure. However, the precise mechanism of contractile dysfunction and dilation is incompletely understood. Here, we investigate the pathogenesis of DSP-R451G, a missense mutation that results in complete degradation of desmoplakin protein. METHODS: We use 3 complementary models to characterize desmoplakin-linked cardiomyopathy: induced pluripotent stem cell-derived engineered heart tissue expr…

Maternal exposure to polystyrene nanoplastics leads to ovotoxicity in female mouse offspring.

Polystyrene nanoplastics (nPS) have been involved in male reproductive health by inducing testicular damage in offspring. However, whether nPS exposure affects reproductive development in female offspring remains poorly understood. Here, we investigated the effects of maternal nPS exposure on ovarian development in offspring. 31 ICR mice were orally administered normal drinking water (control group) or nPS at concentrations of 0.1 µg/ml, 1 µg/ml, and 10 µg/ml in normal drinking water for 11 consecutive weeks, encompassing the pre-mating, mating, pregnancy, and lactation periods. The results sh

Azanucleoside treatment leads to B-cell precursor acute lymphoblastic leukemia.

5-Aza-4'-thio-2'-deoxycytidine (ATC) is an azanucleoside cytidine analog under investigation in preclinical studies for solid tumors as a pr … t methylated cytosines were preferred targets for mutagenesis. This study reveals that ATC exposure leads to both DNMT1-dependent and -independent mutagenesis and provides a direct link between ATC exposure, a complex mutational signature, and malignant transformation.

Multiplexing of cognitive encoding by oculomotor networks leads to incidental gaze shifts.

Humans and other animals are adept at learning to perform cognitively demanding behavioral tasks. Neurophysiological recordings in nonhuman primates during such tasks find that the requisite cognitive variables are encoded strongly in core oculomotor brain regions. Here, we assembled a large dataset-11 monkeys performing an abstract visual categorization task, surveyed across more than 1,000 neural recording sessions-to reveal that this produces a robust but uninstructed behavioral "tell," observed in all subjects and experiments: small, cognitively modulated eye movements. We find that these

Blunt Trauma to the Abdomen Leading to Incarcerated Ventral Hernia: A Case Report.

Traumatic abdominal wall hernias are a rare complication of blunt abdominal trauma, with only a small percentage of cases reported in trauma centers. This report discusses a unique case of a 36-year-old female who developed a de novo incarcerated ventral hernia in the left iliac fossa, following a road traffic accident. The herniation involved a segment of small bowel entrapped in the defect, along with mesenteric tears and hemoperitoneum. The patient underwent emergency laparotomy, during which bowel viability was confirmed and primary repair of the defect was performed without bowel resectio

Stent-induced hypersensitivity leading to refractory in-stent restenosis: a case report.

BACKGROUND: Even in the era of new-generation drug-eluting stents, in-stent restenosis remains a common and challenging problem of percutaneous coronary intervention. Among the many factors that contribute to in-stent restenosis, stent-related hypersensitivity is relatively rare, but may be a significant trigger of chronic refractory in-stent restenosis. Nevertheless, it is difficult to diagnose and assess the stent-related hypersensitivity, and there is no standardized treatment strategy. CASE PRESENTATION: We present the case of a 63-year-old Chinese female who experienced refractory in-ste

Rationalized combinatorial targeting of immune co-receptors leads to tumor regression.

Different co-stimulatory and co-inhibitory molecules influence the dynamicity of an immune response. As their expression levels may collectively decide the amplitude and quality of an anti-tumor immune response, we proposed that the expression of these molecules would be dynamically modulated during a progressive tumor growth and that the study of their expression levels would guide fixing a combinatorial target for anti-tumor immunotherapy. Based on the kinetics of expression of 33 immune molecules within the tumor and draining lymph nodes during RM-1-induced progressive prostate tumor model

Molecular mechanism of aberrant decidualization in adenomyosis leading to reduced endometrial receptivity.

Patients with adenomyosis not only experience a decrease in quality of life as a result of dysmenorrhea and severe monthly flow but they are also rendered infertile. Pregnancy rates are still low among women with adenomyosis, even with assisted reproduction. According to the current study, endometrial receptivity is primarily responsible for the lower conception rate among patients with adenomyosis. Decidualization of endometrial stromal cells is the fundamental requirement for endometrial receptivity and the maintenance of a normal pregnancy, even though endometrial receptivity is made up of

Activity Leads to Topological Phase Transition in 2D Populations of Heterogeneous Oscillators.

Populations of heterogeneous, noisy oscillators on a two-dimensional lattice display short-range order. Here, we show that if the oscillators are allowed to actively move in space, the system undergoes instead a Berezenskii-Kosterlitz-Thouless transition and exhibits quasi-long-range order. This fundamental result connects two paradigmatic models-the XY and Kuramoto models-and provides insight into the emergence of order in active systems.

Impact of DNAH3 deficiency on sperm energy metabolism and motility leading to asthenozoospermia†.

Asthenozoospermia, a prevalent contributor to male infertility, exhibits a multifaceted pathogenesis. This study identified a significant downregulation in sperm dynein heavy chain 3 (DNAH3) protein levels in individuals with asthenozoospermia. To elucidate the role of DNAH3 in asthenozoospermia, we constructed Dnah3-knockout mice, which exhibited asthenozoospermia and sterility. The sperm motility of Dnah3-knockout mice significantly declined compared to wild-type mice. However, spermatozoa from Dnah3-knockout mice displayed normal morphology in hematoxylin and eosin staining and transmission
