Protein extracted from Moringa oleifera Lam. Leaves: Bio-evaluation and characterization as suitable plant-based meat-protein alternative.

This study aimed to isolate and characterize moringa leaf protein (MLP) via HPLC and evaluate its consumption's effects through rat model. Four groups of Albino Wistar rats (n = 25 each) along with a control group (n = 25) were acclimatized. The isolated MLP was added to the basal diet (casein; control) in various percentages (25, 50, 75, 100%) for a 21-day experimental period. On three intervals (1st, 11th, 21st days), blood samples were collected and subjected for hematological and biochemical examination (Renal Function Test (RFT), Liver Function Test (LFT)). MLP contained a variety of essential and non-essential amino acids in substantial amounts. The Protein Efficiency Ratio (PER) of 50% MLP-treated group was the highest (1.72) among MLP treatments. Increases in feed intake and weight were observed in treated rats compared to the control. The hematological profile of the rats revealed increases in Hemoglobin (Hb) (7.9-14.0%), White Blood Cell (WBC) (35.9-51.5%), Red Blood Cell (RBC) (17.1-22.2%), Hematocrit (HCT) (13.1-22.9%), and platelets levels (36.5-40.6%) from day 1. Protein isolates decreased liver parameters but resulted in non-significant changes in liver and kidney functions in rats. Further investigation is needed to determine the safe daily intake of MLP.

Association of autoimmune pancreatitis with Raghib syndrome.

Key Clinical Message: Autoimmune pancreatitis (AIP) is a form of chronic pancreatitis scarcely found in children. Raghib syndrome is a rare congenital heart defect known as persistent left superior vena cava (LSVC) draining into the left atrium. Total signs of Raghib syndrome in AIP case accompanied by an IgG4-related disease were described. Abstract: Autoimmune pancreatitis (AIP) is a form of chronic pancreatitis scarcely found in children. Raghib syndrome is a rare congenital heart defect known as persistent left superior vena cava (LSVC) draining into the left atrium. Here, we describe Raghib syndrome in AIP case accompanied by an IgG4-related disease (AIP/IgG4RD). A 13-year-old boy presented with a 3-month history of fever and abdominal pain. The laboratory findings showed SGOT and SGPT, ALP was increased, while amylase and γ-GT were normal. Immunoglobulins were normal, except for IgG. Endosonography, spiral CT of the abdomen, and cholangiopancreatography showed an enlargement of the pancreas. Contrast echocardiography discovered opacification of the coronary sinus and left atrium. Transesophageal echocardiography for LSVC revealed a dilatation in the coronary sinus, indicating persistent LSVC. Following the injection of agitated saline into the left antecubital vein, bubbles entered both left and right atria in LSVC. It is reasonable to exclude some of these rare disorders as Raghib syndrome, in cases that will be started on medications like corticosteroids, which increases the susceptibility to thromboembolic events.

Study of readiness and performance of nurses in evaluating clinical care and processes of care and nursing.

Background: Clinical care and nursing skills are important issues that can influence the efficacy of treatment, the health of patients, and medical errors. The aim of this study was to investigate the readiness of medical staff in the field of effectiveness and evaluation of clinical care and nursing skills. Materials and methods: This descriptive, cross-sectional study was performed on 99 medical staff working in hospitals from August 2020 to December 2021. The instrument used was a checklist for the effectiveness and evaluation of clinical care based on the findings of the nursing reports. Data were analyzed by statistical software. Results: The mean age of nurses was 37.5 years. Among the participants, 16.3% were male and 85.7% were female; 56.6% of nurses had completed clinical care. The overall performance of nurses in drug-related care and nursing processes was observed to be acceptable. Nurses were successful in performing many aspects of the nursing processes of repulsion, absorption, and dressing and showed good preparation. In relation to gavage, a high percentage of nurses performed the procedure well. However, in some cases, such as medication-related care, handwashing, and the use of personal protective equipment, where there is a possibility of touching the blood or other body fluids of the patients, the performance of nurses was moderate. Conclusion: The findings of this research demonstrated that there are limitations, strengths, and weaknesses in terms of some aspects such as medication, care and nursing processes, compliance with standards, and infection control, which can be considered to improve the performance of nurses in the future.

The mycolic acid reductase Rv2509 has distinct structural motifs and is essential for growth in slow-growing mycobacteria.

The final step in mycolic acid biosynthesis in Mycobacterium tuberculosis is catalysed by mycolyl reductase encoded by the Rv2509 gene. Sequence analysis and homology modelling indicate that Rv2509 belongs to the short-chain fatty acid dehydrogenase/reductase (SDR) family, but with some distinct features that warrant its classification as belonging to a novel family of short-chain dehydrogenases. In particular, the predicted structure revealed a unique α-helical C-terminal region which we demonstrated to be essential for Rv2509 function, though this region did not seem to play any role in protein stabilisation or oligomerisation. We also show that unlike the M. smegmatis homologue which was not essential for growth, Rv2509 was an essential gene in slow-growing mycobacteria. A knockdown strain of the BCG2529 gene, the Rv2509 homologue in Mycobacterium bovis BCG, was unable to grow following the conditional depletion of BCG2529. This conditional depletion also led to a reduction of mature mycolic acid production and accumulation of intermediates derived from 3-oxo-mycolate precursors. Our studies demonstrate novel features of the mycolyl reductase Rv2509 and outline its role in mycobacterial growth, highlighting its potential as a new target for therapies.

Short-course administration of a traditional herbal mixture ameliorates asthma symptoms of the common cold in children.

OBJECTIVE: Asthma is an increasing chronic respiratory disease affecting over 300 million people worldwide. Several studies have shown that herbal remedies may improve asthma control and reduce asthma symptoms. In this study, the effects of short-course administration of an herbal mixture (ASMATUSTM) in asthmatic children during viral respiratory tract infection, were evaluated. MATERIALS AND METHODS: Forty-six children (7-12 years old) with intermittent asthma were enrolled in this double-blind randomized clinical trial. At the onset of common cold symptoms, the patients were randomly assigned to daily receive either the herbal mixture (comprised of Matricaria chamomilla, Althaea officinalis, Malva sylvestris, Hyssopus officinalis, Adiantum capillus-veneris, Glycyrrhiza glabra and Ziziphus jujube) or placebo for 5 days. Primary outcomes included day symptoms, night symptoms, and asthma attacks. Secondary outcomes included Peak Expiratory Flow Rate (PEFR), the need for ß-agonist administration, oral prednisolone usage, necessity for re-visit due to uncontrolled or insupportable symptoms, as well as the number of hospital admissions and days absent from school. RESULTS: the herbal mixture significantly decreased the severity of coughs (p=0.049) and nighttime awakenings (p=0.029) in comparison to placebo. There was no significant reduction in wheezing, tachypnea, respiratory distress, PEF rate, absence from school, outpatient visits, asthma exacerbation, oral prednisolone or ß-agonist usage and hospitalization. CONCLUSION: Short-course of herbal mixture this traditional herbal mixture, starting at the onset of signs of a viral respiratory tract infection in children with intermittent asthma, reduced cough and nights awakening. Further studies should be done to determine the most effective herbal admixture, as well as dose and duration of treatment.

Psychological Signs as the Only Presentation of Wilson's Disease in an 11-Year-Old Boy.

Wilson's disease (WD) is a rare autosomal recessive disease due to copper metabolism disturbance. The clinical presentation spectrum of Wilson's disease is wide and initial findings of the disease depend on the organ involved. Neurologic disorders can develop insidiously or precipitously with intention tremor, dysarthria, rigid dystonia, Parkinsonism, deterioration in school performance or behavioral changes. This article is presenting an 11-yr old boy with chief complaint of falling and upper limb spasm. He referred to the Neurology Department, Ghaem Hospital, Mashhad, northeastern Iran in 2016. His symptoms began from 6 months earlier as mood instability (prolonged spontaneous crying). He was also suffering from occasionally tremor and micrographia. Initial investigations were normal and with diagnosis of depression and psychiatric problems, he had undergone treatment with fluoxetine and risperidone. Wilson's disease should be considered in the diagnosis of all children with psychiatric and musculoskeletal symptoms.

The Effects of Different Repetitive Transcranial Magnetic Stimulation (rTMS) Protocols on Cortical Gene Expression in a Rat Model of Cerebral Ischemic-Reperfusion Injury.

Although repetitive Transcranial Magnetic Stimulation (rTMS) in treatment of stroke in humans has been explored over the past decade the data remain controversial in terms of optimal stimulation parameters and the mechanisms of rTMS long-term effects. This study aimed to explore the potential of different rTMS protocols to induce changes in gene expression in rat cortices after acute ischemic-reperfusion brain injury. The stroke was induced by middle cerebral artery occlusion (MCAO) with subsequent reperfusion. Changes in the expression of 96 genes were examined using low-density expression arrays after MCAO alone and after MCAO combined with 1Hz, 5Hz, continuous (cTBS) and intermittent (iTBS) theta-burst rTMS. rTMS over the lesioned hemisphere was given for two weeks (with a 2-day pause) in a single daily session and a total of 2400 pulses. MCAO alone induced significant upregulation in the expression of 44 genes and downregulation in 10. Two weeks of iTBS induced significant increase in the expression of 52 genes. There were no downregulated genes. 1Hz and 5Hz had no significant effects on gene expression, while cTBS effects were negligible. Upregulated genes included those involved in angiogenesis, inflammation, injury response and cellular repair, structural remodeling, neuroprotection, neurotransmission and neuronal plasticity. The results show that long-term rTMS in acute ischemic-reperfusion brain injury induces complex changes in gene expression that span multiple pathways, which generally promote the recovery. They also demonstrate that induced changes primarily depend on the rTMS frequency (1Hz and 5Hz vs. iTBS) and pattern (cTBS vs. iTBS). The results further underlines the premise that one of the benefits of rTMS application in stroke may be to prime the brain, enhancing its potential to cope with the injury and to rewire. This could further augment its potential to favorably respond to rehabilitation, and to restore some of the loss functions.

Mycolic acids: deciphering and targeting the Achilles' heel of the tubercle bacillus.

Mycolic acids are unique long chain fatty acids found in the lipid-rich cell walls of mycobacteria including the tubercle bacillus Mycobacterium tuberculosis. Essential for viability and virulence, enzymes involved in the biosynthesis of mycolic acids represent novel targets for drug development. This is particularly relevant to the impact on global health given the rise of multidrug resistant and extensively drug resistant strains of M. tuberculosis. In this review, we discuss recent advances in our understanding of how mycolic acid are synthesised, especially the potential role of specialised fatty acid synthase complexes. Also, we examine the role of a recently reported mycolic acid transporter MmpL3 with reference to several reports of the targeting of this transporter by diverse compounds with anti-M. tuberculosis activity. Additionally, we consider recent findings that place mycolic acid biosynthesis in the context of the cell biology of the bacterium, viz its localisation and co-ordination with the bacterial cytoskeleton, and its role beyond maintaining cell envelope integrity.
