In this article, we discuss on the role of the British physician and midwifery practitioner John Clarke (1760-1815) in the characterisation of the various types of seizures and epilepsy and related phenomena ('convulsions') occurring in children. In his unfinished work Commentaries on Some of the Most Important Diseases of Children (1815), Clarke discussed the pathophysiology of convulsions and was the first to describe, 12 years before the French neurologist Louis Francois Bravais (1801-1843) and more than 30 years before the Irish-born physician Robert Bentley Todd (1809-1860), the postictal paresis...

We previously described a structure-based fragment hopping for lead optimization using a pre-docked fragment database, "LeadOp," that conceptually replaced "bad" fragments of a ligand with "good" fragments while leaving the core of the ligand intact thus improving the compound's activity. LeadOp was proven to optimize the query molecules and systematically developed improved analogs for each of our example systems. However, even with the fragment-based design from common building blocks, it is still a challenge for synthesis...

This study assessed the effects of crystalloid versus synthetic colloid in vitro on immune cells co-cultured with mouse splenocytes. Mouse splenocytes were co-cultured with three different types of fluid: Plasma solution-A® (CJ HealthCare, Seoul, Korea; the crystalloid group); Tetraspan 6%® (B. Braun Medical, Melsungen, Germany; the Colloid-T group); and Volulyte 6%® (Fresenius Kabi, Bad Homburg vor dér-Höhe, Germany; Colloid-V group). To evaluate the acquired immune response, cluster of differentiation (CD) 4+ T cells and CD8+ T cells were measured...

OBJECTIVE: Insufficient sleep is common among caregivers and is associated with worse health outcomes; however, the contributors to poor sleep among caregivers are unknown. We investigated the cross-sectional association between socioeconomic status (SES), psychosocial stressors, and sleep among caregivers. METHODS: Caregivers (n=98) of teenagers with asthma self-reported sleep duration (hours), sleep quality (very good to very bad), education (<high school to college graduate), income ($15,000 to $50,000), and psychosocial stressors (stress, worry, social support, depressive symptoms, nightly awakenings due to caregiving)...

Gene editing and CRISPR (a group of repeated DNA sequences in bacteria) typically target disease-causing mutated genes by eliminating the bad gene altogether, by correcting the problem DNA to restore proper gene functioning, or by modifying a different gene to compensate for the faulty gene's lost function. One research group at Duke University in Durham, North Carolina, however, is using a different strategy to fight one of the most common inherited genetic diseases: Duchenne muscular dystrophy (DMD).

Seasonal temperature changes may take organisms to the upper and lower limit of their thermal range, with respective variations in their biochemical and metabolic profile. To elucidate these traits, we investigated metabolic and antioxidant patterns in tissues of sea bream Sparus aurata during seasonal acclimatization for 1 yr in the field. Metabolic patterns were assessed by determining lactate dehydrogenase, citrate synthase, and β-hydroxyacyl CoA dehydrogenase activities, their kinetic properties and plasma levels of glucose, lactate, and triglycerides and tissue succinate levels...

BACKGROUND: General anaesthesia and spinal anaesthesia are commonly used for caesarean sections. The aim of this study was to compare the outcomes from caesarean sections with these two types of anaesthesia. METHODS: In this quasi-controlled trial, we enrolled women undergoing caesarean sections at Al-Helal Al-Emirati Hospital, Rafah, Gaza Strip. Women were assigned either to general anaesthesia (20% intravenous propofol for anaesthesia induction followed by atracurium for muscle relaxation, and nitrous oxide and oxygen for anaesthesia maintenance) or to spinal anaesthesia (0·5% hyperbaric solution bupivacaine with 20 μg fentanyl intrathecally)...

Malignant melanoma is characterized by rapid deterioration, early metastasis and high mortality. Cdk5 regulatory subunit-associated protein 1 (CDK5RAP1), which catalyzes 2-methylthio (ms2 ) modification of mitochondrial transfer RNAs, has been reported to induce cancer cell apoptosis, by a phospho-c-Jun N-terminal kinase (p-JNK) signaling pathway. The present study was the first to report on the association between CDK5RAP1 deficiency and nuclear factor-κB (NF-κB) signaling pathway during the apoptosis process in human malignant melanoma (A375) cells...

Hyperammonemia plays a key role in the pathophysiology of hepatic encephalopathy (HE) and most HE treatments are ammonia-lowering drugs. However, the usefulness of measuring ammonemia in routine practice remains controversial and not recommended systematically even when neurological symptoms are present. First, ammonemia measurement should be carefully performed in order to avoid a falsely elevated result. When performed, a normal ammonemia in a cirrhotic patient with neurological symptoms should lead to reconsider the diagnosis of HE...

CONTEXT: Bariatric surgery has beneficial effects on obesity and associated comorbidities such as glycaemic control in type 2 diabetes, dyslipidaemia, hypertension, and renal and hepatic function. Nevertheless, this surgery is not free of complications and possible side effects due to restrictive and/or malabsorptive related components. CASE DESCRIPTION: We report the case of a 60-year-old woman whose past medical history included morbid obesity, hypertension and Scopinaro biliopancreatic diversion (BPD) with duodenal switch in 1998...

T cells harboring multiple co-inhibitory molecules lose their anti-tumoral functionality. PD-1 is a clinically approved target in cancer therapy, but its expression alone does not mean dysfunctionality. The expression of Tim-3 on numerous cell types (T cell, Treg, dendritic cell, myeloid cells) favors tumor escape to immune cells. Within many tumors, PD-1/Tim-3 coexpressing CD8-T cells lose their ability to secrete cytokines (IFNγ, IL-2, TNFα) and their intratumoral infiltration correlates with a bad prognosis...

Tumour lysis syndrome (TLS) is a rare oncological emergency in solid tumours. Because it is associated with bad short-term prognosis, early recognition and treatment are mandatory. This case refers to a middle-aged woman who presented with stage IV colon cancer, with massive hepatic involvement. After three cycles of first-line FOLFOX (folinic acid, 5-fluorouracil and oxaliplatin), she developed acute kidney injury and hyperkalaemia that did not respond to standard measures. High suspicion of TLS prompted further corroborating investigations and early intensive care unit admission...

The phenotypes of calbindin-D9k - ( CaBP-9k -) knockout (KO), calbindin - D28k - ( CaBP-28k -) KO, and CaBP-9k/28k -KO mice are similar to those of wild-type (WT) mice due to the compensatory action of other calcium transport proteins. In this study, we investigated the expression of cellular prion protein (PrPC ) in the brains of CaBP-9k -, CaBP-28k -, and CaBP-9k/28k -KO mice. PrPC expression was significantly upregulated in the brain of all three strains. Levels of phospho-Akt (Ser473) and phospho-Bad (Ser136) were significantly elevated, but those of phospho-ERK and phospho-Bad (Ser155 and 112) were significantly reduced in the brains of CaBP-9k -, CaBP-28k -, and CaBP-9k/28k -KO mice...

Addictive disorders have a strong psychosocial component in their etiogenesis, and hence psychosocial approaches form a significant part of management planning with a role in prevention, treatment, relapse prevention and long term rehabilitation. Due to a number of myths and misconceptions associated with addictive disorders, there is often strong resistance from the patients as well as the families towards treatment. The disorder is often perceived as a bad habit and hence not requiring treatment. It is very important to break this barrier to bring the patient and the family in treatment engagement...
