Endemic Sideritis dichotoma Huter, herbal tea, is used for colds, coughs and digestive ailments. Since at least 25% of the active ingredients of pharmacological drugs are obtained from plants, it is important to investigate many plants, both traditionally used and whose potential hasnt yet been discovered, before they disappear. When the results compared to other Sideritis species, it has better antioxidant activity in DPPH• scavenging activity, Fe3+ and Cu2+ reducing capacity methods and is also rich in minerals, necessary for human body, K, Mg, Ca, P, S...

OBJECTIVES: Prolonged intubation is a known risk factor of LTS. LTS related to COVID-19 may result in a different phenotype: pronation affects the location of stenosis and COVID-19 pneumonia can decline lung mechanics. Therefore, airway management in these patients may carry unique challenges for both anesthesiologists and surgeons.This prospective observational feasibility trial aims to evaluate the use of a novel thin, cuffed, endotracheal tube (Tritube) in combination with flow-controlled ventilation (FCV) in the management of patients with COVID-19-related LTS undergoing laryngeal surgery...

Mycoplasma pneumoniae is well known to cause pulmonary infection. However, it often has extrapulmonary manifestations as well. We diagnosed and treated a 41-year-old female who presented with symptoms of pneumonia along with multisystem involvement, including rash, acute hepatitis, and new onset heart failure that improved with steroids and doxycycline. Subsequent guideline-directed medical therapy for non-ischemic cardiomyopathy (NICM) coincided with the complete recovery of the left ventricular function in three months...

Amniotic constriction band (ACB) is an uncommon clinical concept with different presentations specific to each patient with clinical symptoms may include ring constrictions, digital defects, natural limb amputations, and visceral defects. The etiology of this defect is not fully understood. We present a full-term newborn boy who was born by vaginal delivery to a healthy mother. At birth, amniotic bands encircled and constricted his upper and lower limbs. At two and six months of gestation, the mother gave a unique obstetric history of recurrent exposure to her infected daughter, which was diagnosed later as a case of atypical M...

UNLABELLED: Multiple pathogenic mechanisms are found in SARS-CoV2 systemic inflammation. Oxidative stress, altered proteolysis, hypercoagulation, and metabolic disorders are significant in virus-induced lesions. The study aimed to investigate the biochemical mechanism of virus-induced disorders and determine the biochemical features in SARS-CoV2-associated liver damage and intestine lesions. A retrospective case series of ninety-two patients diagnosed with COVID-19 pnemonia. The ACE, α1-proteinase inhibitor, trypsin-like proteinase, and elastase activity were measured...

Background Sepsis is defined as life-threatening organ dysfunction due to a dysregulated host response to infection. Septic shock, multi-organ dysfunction, and death occur in severe cases with reduced blood flow to vital organs. Sepsis contributes to 15-20% of all global deaths. Through this study, we intend to evaluate the clinical profile and study the common blood investigatory panels along with organisms causing sepsis in patients presenting with sepsis in the emergency department during the COVID pandemic...

Secondary bacterial infections can exacerbate SARS-CoV-2 infection, but their prevalence and impact remain poorly understood. Here, we established that a mild to moderate infection with the SARS-CoV-2 USA-WA1/2020 strain increased the risk of pneumococcal (type 2 strain D39) coinfection in a time-dependent, but sex-independent, manner in the transgenic K18-hACE2 mouse model of COVID-19. Bacterial coinfection increased lethality when the bacteria was initiated at 5 or 7 d post-virus infection (pvi) but not at 3 d pvi...

Streptococcus pneumoniae is an important causative organism of respiratory tract infections. Although periodontal bacteria have been shown to influence respiratory infections such as aspiration pneumonia, the synergistic effect of S. pneumoniae and Porphyromonas gingivalis , a periodontopathic bacterium, on pneumococcal infections is unclear. To investigate whether P. gingivalis accelerates pneumococcal infections, we tested the effects of inoculating P. gingivalis culture supernatant (PgSup) into S. pneumoniae -infected mice...

Erythema multiforme is a self-limited condition that is characterized by the rapid onset of symmetric targetoid lesions. This hypersensitivity reaction is commonly triggered by herpes simplex virus and Mycoplasma pneumoniae infections. Pembrolizumab is an anti-programmed cell death protein 1 (PD-1) inhibitor that is associated with drug-induced erythema multiforme. Radiotherapy is a rarely reported trigger of erythema multiforme. We report a case of recurrent pembrolizumab and radiotherapy-induced erythema multiforme in a patient with stage IV non-small cell lung cancer...

Ribonucleotide reductase (RNR) is an essential enzyme found in all organisms. The function of RNR is to catalyze the conversion of nucleotides to deoxynucleotides. RNRs rely on metallo-cofactors to oxidize a conserved cysteine in the active site of the enzyme into a thiyl radical, which then initiates nucleotide reduction. The proteins required for MnIII2-Y• cluster formation in class Ib RNR are NrdF (β-subunit) and NrdI (flavodoxin). An oxidant is channeled from the FMN cofactor in NrdI to the dimanganese center in NrdF, where it oxidizes the dimanganese center and a tyrosyl radical (Y•) is formed...

PURPOSE: An outbreak of a novel respiratory disease due to coronavirus species was emerged in 2019 and named as Coronavirus Disease-2019 (COVID-19). Clinical and immunological factors affecting the course of COVID-19 in kidney transplant recipients (KTR) are not well-known. METHODS: In this prospective observational study, we presented 20 KTR with COVID-19 pnemonia and examined the factors predicting the severity of COVID-19. A total of 10 KTR without COVID-19 was used as control group...

Cowpea seed protein hydrolysates (CPH) were output from cowpea seeds applying alcalase® from Bacillus licheniformis . CPH with an elevated level of hydrolysis was fractionated by size exclusion chromatography (SEC). Both CPH and SEC-portions showed to contain antimicrobial peptides (AMPs) as they inhibited both Gram-positive bacteria, such as Listeria monocytogenes LMG10470 (L. monocytogenes) , Listeria innocua . LMG11387 (L. innocua ), Staphylococcus aureus ATCC25923 (S.aureus ), and Streptococcus pyogenes ATCC19615 (St...

The hazardous consequences of electromagnetic field (EMF) exposure represent a public health concern. Common sources of EMF include smartphones and wireless fidelity (Wi-Fi). The aim of our study is to assess whether exposure to Wi-Fi radiofrequency radiation influences the pathogenic traits of carbapenem-resistant Klebsiella pneumoniae. The susceptibility to antibiotics was evaluated by the determination of minimum inhibitory concentrations (MIC). In this study, K. pneumoniae showed a non-linear response to treatments with Colistin and Gentamycin following different Wi-Fi exposure periods...

Mycoplasma pneumoniae is a common cause of community-acquired pneumonia, but it can affect other parts of the body. Due to the varied presentation and lack of readily available specific diagnostic tools, diagnosis is often challenging, which may lead to delay in the treatment and unfavorable outcomes. We describe such a unique case of myocarditis caused by Mycoplasma pneumoniae complicated by left ventricular thrombus and an embolic stroke without the presence of pneumonia. There is a paucity of data regarding Mycoplasma pneumoniae myocarditis and stroke in the absence of pulmonary symptoms especially in adults, calling for further studies for early diagnosis and management...

The non-hazardous silver nanoparticles (AgNPs) synthesised using the extract of a biological organism has gained widespread attention for various applications, mainly in healthcare. This study aimed at synthesising AgNPs using the aqueous extract of Marphysa moribidii (Annelida, Polychaeta) and to evaluate their antibacterial activities. AgNPs were synthesised in response to silver nitrate (AgNO3 ) with polychaete crude extract for 24 h incubation; the polychaete crude extract acted as both reducing and stabilising agents...

An outbreak of a novel coronavirus disease-19 (nCoV-19) infection began in December 2019 in Wuhan, China, and now involved the whole word. Several health workers have been infected in different countries. We report the case of a young man with documented nCoV-19 infection evaluated with lung ultrasound and discuss potential applications of lung ultrasound in this setting. Lung ultrasound allowed the identification of nCoV-19 infection at bed-side. Moreover, lung ultrasound can have several other advantages, such as reduced health worker exposition to infected patients, repeatability during follow-up, low-costs and easier application in low-resource settings...

Background: Resistance to antimicrobial agents of pathogenic bacteria has become a major problem in routine medical practices. Carbapenem resistance has long been increasing. The production of carbapenem- hydrolysing β-lactamases (carbapenamases), which include NDM, KPC, OXA-48, IMP-1 and VIM is the most common mechanism. Case presentation: A 56 years old male presented with fever and mental changes with progressively decreasing sensorium for the last 3 days...

Streptococcus pnemoniae is a major cause of morbidity and mortality among splenectomised patients with β-thalassemia major. We have previously shown that a 13-valent pneumococcal conjugate vaccine (PCV13) induces robust early immune responses in such patients, while history of repeated immunisations with the 23-valent polysaccharide pneumococcal vaccine (PPSV23) results in attenuation of the response to PCV13. However, the duration of vaccine-induced protection in splenectomised thalassemic patients and the associated need for booster immunisation remains unclear...
