Epaltes mexicana is a plant widely used in traditional medicine and as a food in Mexico; however, its phytochemical and pharmacological studies are limited. This study aimed to identify the active secondary metabolites of Epaltes mexicana and determine its cytotoxic activity on cancer cell lines. Three organic extracts were obtained by maceration using n-hexane, dichloromethane, and methanol.

Purpose: Concurrent chemoradiotherapy (cCRT) is the standard treatment for locally advanced and unresectable non-small-cell lung cancer. Population is aging, and Geriatric assessment (GA) has demonstrated its paper to select fit patients for active treatment and vulnerable, frail patients for interventions and/or palliative care in many histologies. Its role in locally advanced, unresectable non-small-cell lung cancer has been less explored.

For this study, procyanidins generated through the autoxidation of (-)-epicatechin (Flavan-3-ol) under mildly acidic conditions (pH = 6.0) were characterized with ultra high-performance liquid chromatography (UHPLC) coupled with tandem mass spectrometry (MS/MS). Two procyanidins (types A and B) and a mix of oligomers were generated through the autoxidation of (-)-epicatechin.

Background: The arrival of large quantities of in the Mexican Caribbean Sea has generated major environmental, health and economic problems. Although has been used in the generation of some commercial products, few studies have described its possible applications as a source of compounds with anticancer activity.

Objective: This study aimed to evaluate the antiproliferative effects of different extracts on various cancer cell lines.

Biological treatments have become insufficient to treat municipal wastewater with greater toxicity and excess nitrogen and phosphate species, thus affecting the organisms that consume the water. In this work, a process was implemented for the removal of nutrients through three stages: stage A, complete aeration (24 h, 43 months); stage B, decreased aeration (12 h, 17 months); and stage C, decreased aeration with biocalcium (12 h, 19 months). The addition of biocalcium from eggshell promoted the formation of flocks, which resulted in the removal of nitrites (61 %), nitrates (84 %), total nitrogen (57 %), total phosphorus (8.

The spike (S) protein of SARS-CoV-2 is a molecular target of great interest for developing drug therapies against COVID-19 because S is responsible for the interaction of the virus with the host cell receptor. Currently, there is no outpatient safety treatment for COVID-19 disease. Furthermore, we consider it of worthy importance to evaluate experimentally the possible interaction of drugs (approved by the Food and Drug Administration) and the S, considering some previously in silico and clinical use.

Background/objectives: Cocoa consumption is associated with health benefits due to its high content of polyphenols. However, the effects of short-term cocoa consumption remain unclear. We aimed to determine the effects generated by cocoa consumption (for 7 days) in young adults in normoweight and class II obesity.

The mechanism is unclear for the reported protective effect of hyperbaric oxygen preconditioning against oxidative stress in tissues, and the distinct effects of hyperbaric oxygen applied after stress. The trained mice were divided into three groups: the control, hyperbaric oxygenation preconditioning, and hyperbaric oxygenation applied after mild (fasting) or hard (prolonged exercise) stress. After preconditioning, we observed a decrease in basal levels of nitric oxide, tetrahydrobiopterin, and catalase despite the drastic increase in inducible and endothelial nitric oxide synthases.

Introduction: On the basis of the findings of the phase 3 PACIFIC trial (NCT02125461), durvalumab is standard of care for patients with stage III, unresectable NSCLC and no disease progression after concurrent chemoradiotherapy (cCRT). Many patients are considered unsuitable for cCRT owing to concerns with tolerability. The phase 2 PACIFIC-6 trial (NCT03693300) evaluates the safety and tolerability of durvalumab after sequential CRT (sCRT).

Breast cancer (BC) is the most frequently diagnosed cancer and is the second-most common cause of death in women worldwide. Because of this, the search for new drugs and targeted therapy to treat BC is an urgent and global need. Histone deacetylase 6 (HDAC6) is a promising anti-BC drug target associated with its development and progression.

Introduction: Management of donor site morbidity in the setting of split thickness skin graft (STSG) is of crucial importance with no superior wound dressing described to date and the growing need of decreasing epithelializing time. The purpose of the study was to compare the standard of care using a hydrocolloid dressing to platelet rich plasma (PRP) and plasma rich in growth factors (PRGF) in order to determine its therapeutic potential in this setting.

Methods: A randomized clinical trial was conducted in which each patient served as its own control.

Numerous targeted therapies have been evaluated for the treatment of non-small cell lung cancer (NSCLC). To date, however, only a few agents have shown promising results. Recent advances in cancer immunotherapy, most notably immune checkpoint inhibitors (ICI), have transformed the treatment scenario for these patients.

Background And Objectives: The excess of body fat and muscle mass loss in adulthood results in sarcopenic obesity, which is associated with disability and poor physical condition. A relationship among obesity, sarcopenia and oxidative stress also has been established. These aspects limit a good muscle function which is crucial in the independence of older women with and without sarcopenic obesity.

Background: Studies of patients with cancer affected by coronavirus disease 2019 (COVID-19) are needed to assess the impact of the disease in this sensitive population, and the influence of different cancer treatments on the COVID-19 infection and seroconversion.

Material And Methods: We performed a retrospective analysis of all patients hospitalized with RT-PCR positive for COVID-19 in our region to assess the prevalence of cancer patients and describe their characteristics and evolution (Cohort 1). Concurrently, a transversal study was carried out in patients on active systemic cancer treatment for symptomatology and seroprevalence (IgG/IgM by ELISA-method) against Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) (Cohort 2).

In order to solve the trajectory tracking task in a wheeled mobile robot (WMR), a dynamic three-level controller is presented in this paper. The controller considers the mechanical structure, actuators, and power stage subsystems. Such a controller is designed as follows: At the high level is a dynamic control for the WMR (differential drive type).

Introduction: Receptor activator of NF-kB ligand stimulates NF-kB-dependent cell signaling and acts as the primary signal for bone resorption. Retrospective analysis of a large trial comparing denosumab versus zoledronic acid in bone metastatic solid tumors suggested significant overall survival (OS) advantage for patients with lung cancer with denosumab (p = 0.01).

(-)-Epicatechin is a phenolic compound with antioxidant activity that is present in natural food and drinks, such as cocoa and red wine. Evidence suggests that (-)-epicatechin exhibits anticancer activity; however, its mechanism of action is poorly understood. Here, we investigated the anticancer effects of (-)-epicatechin and its mechanism of action in breast cancer cells.

Olive pollen is the main cause of pollinosis in Mediterranean countries. The immunological analysis of Ole e 1, the major allergen of Olea europaea, has usually carried out by means of ELISA (Enzyme-Linked ImmunoSorbent Assay). However, most published works only specify the methodology related to antigen quantifications, but not the related to protein extraction.

The upper limb is involved in burns in a high percentage of cases and its reconstruction is extremely important, given the functional impact of this anatomical region. Among the reconstruction choices for severe and large structural defects, the pedicled anterolateral thigh flap is an available option. This case study discusses the utilization of the pedicled anterolateral thigh flap for reconstruction of a complex full-thickness hand burn, when adequate arterial perforators were not available.
