"NeuroVanguard": a contemporary strategy in neuromonitoring for severe adult brain injury patients.

Severe acute brain injuries, stemming from trauma, ischemia or hemorrhage, remain a significant global healthcare concern due to their association with high morbidity and mortality rates. Accurate assessment of secondary brain injuries severity is pivotal for tailor adequate therapies in such patients. Together with neurological examination and brain imaging, monitoring of systemic secondary brain injuries is relatively straightforward and should be implemented in all patients, according to local resources.

Functional, immunological characterization, and anticancer activity of BaMtx: A new Lys49- PLA homologue isolated from the venom of Peruvian Bothrops atrox snake (Serpentes: Viperidae).

Bothorps atrox is responsible for most of the ophidism cases in Perú. As part of the envenoming, myotoxicity is one of the most recurrent and destructive effects. In this study, a myotoxin, named BaMtx, was purified from B.

Chikungunya encephalitis, a case series from an endemic country.

Background: The Chikungunya Virus (CHIKV) was introduced into Honduras in 2015. Since then the WHO has reported more than 14,000 suspected cases in the country.

Objective: To describe the clinical, laboratory, neuroimaging, and pathological features of CHIKV encephalitis.

Fibrinogen-clotting enzyme, pictobin, from Bothrops pictus snake venom. Structural and functional characterization.

A thrombin-like enzyme, pictobin, was purified from Bothrops pictus snake venom. It is a 41-kDa monomeric glycoprotein as showed by mass spectrometry and contains approx. 45% carbohydrate by mass which could be removed with N-glycosidase.

Spatial distribution of dengue in Honduras during 2016-2019 using a geographic information systems (GIS)-Dengue epidemic implications for public health and travel medicine.

Background: After serious epidemics of chikungunya (CHIKV) and Zika (ZIKV) in the Americas, dengue (DENV) have reemerged in most countries. We analyzed the incidence, incidence rates, and evolution of DENV cases in Honduras from 2015 to 2018 and the ongoing 2019 epidemic.

Methods: Using epidemiological weeks (EW) surveillance data on the DENV in Honduras, we estimated incidence rates (cases/100,000 population), and developed maps at national, departmental, and municipal levels.

Biochemical and molecular characterization of the hyaluronidase from Bothrops atrox Peruvian snake venom.

Snake venoms are a rich source of enzymes such as metalloproteinases, serine proteinases phospholipases A2 and myotoxins, that have been well characterized structurally and functionally. However, hyaluronidases (E.C.

Biochemical, biological and molecular characterization of an L-Amino acid oxidase (LAAO) purified from Bothrops pictus Peruvian snake venom.

An L-amino acid oxidase from Peruvian Bothrops pictus (Bpic-LAAO) snake venom was purified using a combination of size-exclusion and ion-exchange chromatography. Bpic-LAAO is a homodimeric glycosylated flavoprotein with molecular mass of ∼65 kDa under reducing conditions and ∼132 kDa in its native form as analyzed by SDS-PAGE and gel filtration chromatography, respectively. N-terminal amino acid sequencing showed highly conserved residues in a glutamine-rich motif related to binding substrate.

[Characterization of thrombin like enzyme FROM Bothrops pictus venom].

Objectives: To perform a biochemical and molecular characterization of the coagulant principle from Bothrops pictus venom.

Materials And Methods: We amplified the genetic sequence of this enzyme from cDNA and analyzed the homology of its nucleotide sequence and its deduced protein. This enzyme was also purified for N-terminal sequencing of first 20 amino acids and for coagulation assays using human plasma and human fibrinogen.

Effect of early diabetes on the expression of alpha-1 adrenergic receptors in aorta and carotid arteries of Wistar Kyoto and spontaneously hypertensive rats.

Hypertension and diabetes have been related to noradrenergic system impairment, especially to the response mediated by alpha-1 receptors. The aim of this work was to investigate possible changes in the expression of alpha-1 adrenergic receptors in aorta and carotid arteries of Wistar Kyoto and spontaneously hypertensive rats after 4 weeks of the onset of diabetes. Our results suggest that early diabetes modifies the expression of alpha-1 adrenergic receptors in aorta and carotid arteries of both WKY and SHR strains in a different way.

[Experimental efficacy of IgY antibodies produced in eggs against the venom of the Peruvian snake Bothrops atrox].

Objectives: To develop an immunization protocol in order to produce avian IgY immunoglobulins against Bothrops atrox Peruvian snake venom and to evaluate its neutralizing capacity.

Materials And Methods: Six Hy Line Brown hens were immunized each two weeks using 500μg/doses of B. atrox venom in a period of two months.

Phase II trial of induction irinotecan-cisplatin followed by concurrent irinotecan-cisplatin and radiotherapy for unresectable, locally advanced gastric and oesophageal-gastric junction adenocarcinoma.

Purpose: The prognosis of patients with unresectable M0 gastric cancer remains very poor. We performed a phase II trial to explore the efficacy and toxicity of induction irinotecan-cisplatin (IC) followed by concurrent irinotecan-cisplatin and radiotherapy (IC/RT) in this setting.

Methods And Materials: Patients with unresectable M0 gastric (GC) or oesophageal-gastric junction (EGJC) adenocarcinomas were treated with two courses of IC (irinotecan, 65 mg/m(2); cisplatin, 30 mg/m(2) on days 1 and 8 every 21 days) followed by IC/RT (daily radiotherapy-45 Gy-with concurrent IC: irinotecan, 65 mg/m(2), and cisplatin, 30 mg/m(2), on days 1, 8, 15, and 22).

[Pancreatic and periampullary tumors: morbidity, mortality, functional results and long-term survival].

Aims: To evaluate postoperative morbidity and mortality, pancreatic function and long-term survival in patients with surgically treated pancreatic or periampullar tumours.

Patients And Methods: Cohort study including 160 patients consecutively operated on: 80 pancreaticoduodenectomies (PD), 30 distal pancreatectomies (DP), 7 total pancreatectomies, 4 central pancreatic resections and 3 ampullectomies. The tumour was not resected in 36 patients.

Phase II trial of preoperative irinotecan-cisplatin followed by concurrent irinotecan-cisplatin and radiotherapy for resectable locally advanced gastric and esophagogastric junction adenocarcinoma.

Purpose: To determine in a Phase II trial whether preoperative irinotecan-cisplatin (IC) followed by concurrent IC therapy and radiotherapy (IC/RT) improved outcome in patients with resectable, locally advanced gastric adenocarcinoma (GC) or esophagogastric junction cancer (EGJC).

Patients And Methods: Patients with resectable Stage II-IV, M0 GC or EGJC made up the study population. The primary endpoint was pathologic complete response (pCR).

Interaction of a plasminogen activator proteinase, LV-PA with human alpha2-macroglobulin.

Lachesis venom plasminogen activator (LV-PA) is a 33-kDa serine proteinase isolated from bushmaster (Lachesis muta muta) snake venom, which activates the fibrinolytic system in vitro. This study has examined the effect of the plasma proteinase inhibitor alpha2-macroglobulin (alpha2-M) towards LV-PA and compares it with the effect on tissue type plasminogen activator (t-PA). The proteolytic activity of LV-PA alone or previously incubated with human plasminogen (Plg) on the large molecular mass protein substrates, dimethylcasein (DMC) and fibrinogen (Fg) was completely inhibited by human alpha2-M.
