Influence of Cardiovascular Risk Factors in Early Relapsing-Remitting Multiple Sclerosis: A Retrospective Analysis.

Prior studies have suggested that cardiovascular risk factors (CVRFs) can affect the prognosis of multiple sclerosis (MS). The aim of this study was to assess if CVRFs affect the early course of MS.

miR-506-3p relieves neuropathic pain following brachial plexus avulsion via mitigating microglial activation through targeting the CCL2-CCR2 axis.

Neuroinflammation results in neuropathic pain following brachial plexus avulsion (BPA). This research was designed for investigating the function of miR-506-3p in BPA-induced neuropathic pain (NP). A total brachial plexus root avulsion (tBPRA) model was produced in adult rats as well as IL-1β-treated motoneuron-like NSC-34 cells and the LPS-treated microglia cell line BV2 for in vivo and in vitro experiments, respectively. RT-PCR and western blot were performed to detect the profiles of miR-506-3p, CCL2 and CCR2, NF-κB, FOXO3a, TNF-α, IL-1β, and IL-6 in cells or the spinal cord close to the tBPI lesion. Neuronal apoptosis was evaluated by immunohistochemistry (IHC) in vivo. CCK8, TUNEL staining, and the LDH kit were adopted for the evaluation of neuronal viability or damage in vitro. RNA immunoprecipitation (RIP) and dual-luciferase reporter gene assays analyzed the targeted association between miR-506-3p and CCL2. As shown by the data, miR-506-3p was vigorously less expressed, while CCL2-CCR2, NF-κB TNF-α, IL-1β, and IL-6 were up-regulated in the spinal cord with tBPI. Overexpression of miR-506-3p attenuated neuronal apoptosis and microglial inflammation. Mechanistically, CCL2 was a downstream target of miR-506-3p. Up-regulating miR-506-3p dampened CCL2-CCR2 and NF-κB activation in the spinal cord and microglia. miR-506-3p had neuroprotective and inflammation-fighting functions in the tBPI rat model via CCL2/CCR2/NF-κB axis.

Chronic Granulomatous schistosomal cholecystitis in Non-endemic zone, a rare one: A case report.

Moynihan's aphorism that "gall stone is a tomb stone erected in the memory of the organism with in it" is true even today. This case could be an example to reemphasise the forementioned axiom. We present here a case of Chronic Granulomatous Schistosomal cholecystitis which is an unusually rare cause of Cholecystitis and cholelithiasis, that too in a non-endemic area. The patient has never ever visited the known endemic zones of Schistosomiasis or Bilharziasis areas in India. In a way it could be the first case report of schistosomiasis in this area.

Alterations in Functional Connectivity of Thalamus and Primary Somatosensory Cortex in Painful and Painless Diabetic Peripheral Neuropathy.

In this study we aimed to investigate the functional connectivity of brain regions involved in sensory processing in diabetes with and without painful and painless diabetic peripheral neuropathy (DPN) and the association with peripheral nerve function and pain intensity.

Red Light-Mediated Photoredox Catalysis Triggers Nitric Oxide Release for Treatment of Induced Intervertebral Disc Degeneration.

Intervertebral disc degeneration (IVDD) has been known as a highly prevalent and disabling disease, which is one of the main causes of low back pain and disability. Unfortunately, there is no effective cure to treat this formidable disease, and surgical interventions are typically applied. Herein, we report that the local administration of nitric oxide (NO)-releasing micellar nanoparticles can efficiently treat IVDD associated with Modic changes in a rat model established by infection with (). By covalent incorporation of palladium(II) meso-tetraphenyltetrabenzoporphyrin photocatalyst and coumarin-based NO donors into the core of micellar nanoparticles, we demonstrate that the activation of the UV-absorbing coumarin-based NO donors can be achieved under red light irradiation via photoredox catalysis, although it remains a great challenge to implement photoredox catalysis reactions in biological conditions due to the complex microenvironments. Notably, the local delivery of NO can not only efficiently eradicate pathogens but also inhibit the inflammatory response and osteoclast differentiation in the intervertebral disc tissues, exerting antibacterial, anti-inflammatory, and antiosteoclastogenesis effects. This work provides a feasible means to efficiently treat IVDD by the local administration of NO signaling molecules without resorting to a surgical approach.

Cannabis in Cancer Survivors Who Report High Impact Chronic Pain: Findings from a 1500+ Patient Survey.

Chronic pain in cancer survivors negatively impacts quality of life. This study sought to investigate the relationship between high-impact chronic pain (HICP) — defined as chronic pain that limits life or work activities on most days or every day in the past 3 months — and cannabis in cancer survivors.

COVID-19 vaccine short-term adverse events in the real-life family practice in Krakow, Poland.

In manufacturers' trials, vaccination against COVID-19 proved to be safe and effective. The officially reported frequency of vaccine adverse events (VAEs) in Poland is lower than that declared by the manufacturers. The anti-vaccination activists questioned the trustworthiness of official data.

Impact of analgesic regimen on patient outcome following subarachnoid hemorrhage: positive adjuvant effects of metamizole.

Various analgesics are used to control intense headaches in patients following subarachnoid hemorrhage. In addition to pain control, it has been shown that some analgesics can affect various pathophysiological cascades. Therefore, we devised a study to assess whether the use of metamizole has a significant impact on the development of ischemic complications, hydrocephalus, and the overall outcome in patients following aneurysmal subarachnoid hemorrhage in the context of the other non-opioids and opioids effects.

Determination of Firocoxib and Its Related Substances in Bulk Drug Substance Batches of Firocoxib by a High-Speed Reversed-Phase HPLC Method With a Short Fused-Core Biphenyl Column.

Firocoxib is a nonsteroidal anti-inflammatory drug. It provides control of postoperative pain and inflammation associated with soft tissue and orthopedic surgery in dogs, and control of pain and inflammation associated with osteoarthritis in horses. A high-speed stability-indicating reversed-phase high-performance liquid chromatography method was developed to determine firocoxib and its related substances in bulk batches of firocoxib drug substance. Firocoxib was dissolved in neat acetonitrile (ACN) and analyzed on a short HALO (fused-core) biphenyl column (30 × 4.6 mm i.d., 2.7-μm particle size) at flow rate of 2.5 mL/min. Column temperature was maintained at 50°C. Mobile phase A is composed of 0.1% of H3PO4 in water and mobile phase B is composed of ACN. Analytes were detected with UV detection at 240 nm and quantitated against an external reference standard. Firocoxib and its related compounds were adequately separated within 4 min by a gradient elution. The method was validated for specificity, linearity, accuracy, precision and robustness according to method validation guidelines described in The International Conference on Harmonization. The validation data demonstrated that this method is sensitive, accurate, robust, specific and stability-indicating.
