Asociación del signo de Moore con la presencia de absceso profundo de cuello de espacio retrofaríngeo.

Background: Deep neck abscesses can cause life-threatening complications. They are diagnosed by physical examination, and contrasted tomography as the gold standard. There are no studies about the association of Moore's sign with infections of the retropharyngeal space.

Mental health impacts of nurses caring for patients with COVID-19 in Peru: Fear of contagion, generalized anxiety, and physical-cognitive fatigue.

The health crisis caused by COVID-19 has resulted in the physical and emotional deterioration of health personnel, especially nurses, whose emotional state is affected by the high risk of contagion, the high demands of health services, and the exhausting working hours. The objective of this research was to determine the relationship between fear, anxiety, and fatigue of nurses caring for patients with COVID-19 in a second level public hospital in Peru. This study presents a quantitative approach and correlational level, cross-sectional, and non-experimental design.

Active Shiga-Like Toxin Produced by Some spp., Isolated in Mexico City.

Shiga-like toxins (Stx) represent a group of bacterial toxins involved in human and animal diseases. Stx is produced by enterohemorrhagic type 1, , and spp.; Stx is an important cause of bloody diarrhea and hemolytic uremic syndrome (HUS).

[Irritable Bowel Syndrome; gut microbiota and probiotic therapy].

Irritable bowel syndrome (IBS) is characterized by symptoms of abdominal pain and altered bowel habits. This common disorder is managed by varying clinical styles as no dominant therapeutic strategy has emerged. The pathophysiology of IBS remains unknown, but several lines of evidence link this disorder with the gut microbiota.

Direct and bystander radiation effects: a biophysical model and clinical perspectives.

In planning treatment for each new patient, radiation oncologists pay attention to the aspects that they control. Thus their attention is usually focused on volume and dose. The dilemma for the physician is how to protract the treatment in a way that maximizes control of the tumor and minimizes normal tissue injury.

Incidence of hypercalcemia, hypercalciuria and related factors in patients treated with recombinant human parathyroid hormone (1-84).

Aim: The aim of this paper was to determine the incidence of hypercalcemia and hypercalciuria (and related factors) in 22 postmenopausal women with osteoporosis treated with PTH (1-84) in daily practice.

Methods: Osteoporosis was defined as history of osteoporotic fracture or a T score less than -3 SD on bone densitometry. Patients were treated with PTH (1-84), 100 mcg/daily, for 12 months.

Synthesis of glycyrrhetinic acid derivatives for the treatment of metabolic diseases.

The effect of glycyrrhetinic acid (GA) and GA-derivatives towards 11beta-hydroxysteroid dehydrogenase (11beta-HSD) was investigated. Novel compounds with modifications at positions C-3, C-11 and C-29 of the GA skeleton were prepared. Single crystal X-ray diffraction data of selected substances are reported and discussed.

Efficient synthesis of glycyrrhetinic acid glycoside/glucuronide derivatives using silver zeolite as promoter.

3-O-Glycopyranosides of glycyrrhetinic acid have been synthesized in good to high yields and excellent stereoselectivity using glycosyl bromide donors and silver zeolite as promoter. In addition to the preparation of glycosides containing beta-linked glucosyl, 2-deoxy-2-trichloroacetamido-glucosyl, galactosyl, cellobiosyl and lactosyl residues, also the deactivated acetylated methyl glucopyranosyluronate bromide donor could be coupled to triterpene aglycon ester derivatives in good yields. The ester protecting group located at C-30 of the oleanolic acid scaffold exerted an influence on the overall yield, with the methylester-protected glycosyl acceptor giving better yields compared to the allyl, benzyl as well as diphenylmethyl ester aglycon.

Human updating of visual motion direction during head rotations.

Previous studies have demonstrated that human subjects update the location of visual targets for saccades after head and body movements and in the absence of visual feedback. This phenomenon is known as spatial updating. Here we investigated whether a similar mechanism exists for the perception of motion direction.

[Heart failure as the initial cardiac manifestation of Steinert's myotonic dystrophy].

The relationship between neuromuscular diseases and the heart has been well known for many years. Cardiac lesions tend to involve the specialized conducting system. We report the case of a 36-year-old male diagnosed with Steinert's myotonic dystrophy whose initial cardiovascular symptom was heart failure and not symptoms related to alterations of the specialized conducting system.

[Creatine kinase increases after coronary interventions].

Introduction And Objectives: Percutaneous revascularization has led to an important change in the treatment of patients with symptomatic ischemic heart disease in recent years. There is controversy concerning the incidence and prognostic significance of postprocedural increases in creatine kinase. The aim of this study was to assess the incidence of these elevations and the related factors and to observe the prognosis of patients with and without creatin kinase elevations.

[Quality control and improvement of the care provided to the patient with acute myocardial infarction. Implementation of a quality assurance program].

Effect of DT-TX 30, a combined thromboxane synthase inhibitor and thromboxane receptor antagonist, on retinal vascularity in experimental diabetes mellitus.

Combined thromboxane synthase inhibitors and thromboxane receptors antagonists have been shown to have a beneficial effect on different models of thrombosis in vivo. We studied the action of one of these compounds (DT-TX 30) compared with dazoxiben (a thromboxane synthase inhibitor) on retinal vascularity in streptozotocin-diabetic rats. Ten nondiabetic animals were treated with isotonic saline, 30 (10 animals per group) were given 0.

[Pneumopericardium in an asthmatic patient. A case report and review of the bibliography].

Pneumopericardium is an uncommon but potentially serious condition of which leading cause is mechanical ventilation in infants suffering respiratory distress syndrome. In adults, however, the most common causes are iatrogenic in diagnostic and therapeutic procedures, as well as traumatic lesions. We describe a case of pneumopericardium in a teenager suffering an asthma crisis.

p53-mediated up-regulation of CD95 is not involved in genotoxic drug-induced apoptosis of human breast tumor cells.

Induction of CD95 (Fas/APO-1) and CD95 ligand during chemotherapeutic treatment may contribute to the death by apoptosis of some tumor cells. In this study, we have analyzed the role of the CD95 system in genotoxic drug-induced death of human breast tumor cells. Incubation of the breast tumor cell lines MCF-7 and EVSA-T with doxorubicin or methotrexate caused apoptosis after 48 h of treatment.

Effect of WEB 2086-BS, an antagonist of platelet-activating factor receptors, on retinal vascularity in diabetic rats.

Specific antagonists of platelet-activating factor (PAF) receptors inhibit platelet aggregation and thromboxane synthesis. These two processes have been implicated in the course of diabetic retinopathy. We assessed the effect of a specific PAF receptor antagonist, WEB 2086-BS (3-(4-(2-chlorophenyl)-9-methyl-6H-thieno(3,2-f) (1,2,4 triazolo-(4,3-a(1,4)-diazepine-2-yl)-1-(4-morpholinyl)-1-propanone) on retinal vascularity in a model of experimental streptozocin-induced diabetes in rats.

Importance of poly(ADP-ribose) polymerase and its cleavage in apoptosis. Lesson from an uncleavable mutant.

We have studied the apoptotic response of poly(ADP-ribose) polymerase (PARP)-/- cells to different inducers and the consequences of the expression of an uncleavable mutant of PARP on the apoptotic process. The absence of PARP drastically increases the sensitivity of primary bone marrow PARP-/- cells to apoptosis induced by an alkylating agent but not by a topoisomerase I inhibitor CPT-11 or by interleukin-3 removal. cDNA of wild type or of an uncleavable PARP mutant (D214A-PARP) has been introduced into PARP-/- fibroblasts, which were exposed to anti-CD95 or an alkylating agent to induce apoptosis.

Effect of camonagrel, a selective thromboxane synthase inhibitor, on retinal vascularization in experimental diabetes.

Platelet hyperactivity accompanied by an increased synthesis of thromboxane and/or a decreased prostacyclin production are important factors in ischemic diabetic retinopathy. We studied the effect of camonagrel and dazoxiben, two thromboxane synthase inhibitors, on retinal vascularization in a model of streptozotocin-induced diabetes in rats. Ten nondiabetic rats, 10 diabetic animals treated with saline (i.

Activation of protein kinase C attenuates early signals in Fas-mediated apoptosis.

Activation of protein kinase C (PKC) has been reported to inhibit Fas (APO-1, CD95)-mediated apoptosis in different cellular systems. Human Jurkat leukemic T cells express the Fas antigen in the cell membrane and undergo apoptosis upon cross-linking by anti-Fas monoclonal antibodies (mAb). Cleavage of the apoptosis-associated protease CPP32 and its substrate poly(ADP-ribose)polymerase are observed after the engagement of Fas antigen with mAb.

Reactive oxygen intermediate(s) (ROI): common mediator(s) of poly(ADP-ribose)polymerase (PARP) cleavage and apoptosis.

HL-60 acute myeloblastic and U937 monoblastoid leukaemic cell lines both cleave poly(ADP-ribose)polymerase (PARP), at the onset of apoptosis, in response to a wide range of cytotoxic agents. This appears to be a common feature of leukaemic cell apoptosis. However, in the chronic myelogenous leukaemic (CML) derived cell line, K562, no such cleavage was detectable.

Stimulation of phosphatidylinositol turnover is a key event for Fas-dependent, activation-induced apoptosis in human T lymphocytes.

We have analyzed the requirements for activation-induced apoptosis in Jurkat T cells expressing the heterologous human muscarinic type 1 receptor (HM1R; J-HM1-2.2 cells) that is coupled to phosphatidylinositol turnover through a protein tyrosine kinase-independent, G protein-regulated mechanism. Triggering of HM1R with the agonist carbachol is sufficient to induce apoptosis in J-HM1-2.

Positivity of patch tests in cutaneous reaction to aminocaproic acid: two case reports.

We observed two cases of maculopapular eruption occurring 12-72 h after the administration of aminocaproic acid (ACA). Patch tests performed with ACA were positive. Clinical and allergologic patterns suggest the type IV mechanism of hypersensitivity.
