The present article studies the policy, numbers, and costs of disaster risk management (DRM) in Mexico, a country highly exposed to climate change, due to two oceans warming up. The PEISOR methodology facilitates interrelating complex interactions and pressures between the natural and the societal system (P), where dangerous effects (E) occur in extreme events, such as floods, landslides, and drought. The impacts (I) of global warming, the pressure of historical poverty, and vulnerable regions were affected by the [...]

Molecular markers play a crucial role in accelerating crop production for sustainable agriculture by identifying resistant traits and enhancing genetic diversity. In this review, we examine the impact of the molecular markers on advancing our understanding of stress tolerance mechanisms in plants, addressing the pressing imperative to bolster global food production to meet the escalating demands of the growing population. Additionally, the application of molecular markers to evaluate the genetic accuracy of plants [...]

One way to increase solar photovoltaic penetration in the grid is the management of voltage fluctuations. This is because a photovoltaic plant cannot be interconnected to the grid if it causes voltage violations. Voltage violation is where voltage exceeds the acceptable range. Often, grid operators request photovoltaic plant owners to regulate voltage sufficiently with expensive and space-consuming static Var compensators. Unfortunately, this sometimes makes the project less feasible. This paper argues that there a [...]

Background: Perfusion imaging, mainly MR perfusion (MRP), is performed frequently for brain tumor imaging. CT perfusion (CTP) is less studied as a method for characterizing brain tumors. The purpose of this study was to demonstrate the usefulness of CTP perfusion parameters in evaluating brain tumors and to compare it with MRP measures in the same patient population. Methods: Patients underwent CTP and MRP imaging prospectively. Images were processed with vendor-provided and vendor-neutral software. Four regions of [...]

Background: Extended criteria donors and donation after cardiac death donors provide organs which tend to be more sensitive to the stress of preservation. There is a lack of evidence about the potential role of oxygen in preservation techniques, and literature comparing oxygenated and non-oxygenated techniques is very limited. The aim of the study was to compare HMP with oxygen versus HMP without oxygen in a pig model of kidney auto-transplantation (KT) reproducing conditions of DCD. We have also set up miRNAs expr [...]

It is important to understand the band offsets between semiconductors, which are crucial to determine the direction of electron transfer at the interfaces. Two methods are normally used to determine the direction from the first principles: alternating slabs put in contact (without empty spaces between them) and separate calculations for each material surface in the presence of vacuum spaces. The first method may introduce distortions due to insufficient epitaxial match, which may lead to bandgap changes, and the se [...]

Background: Hepatocellular carcinoma (HCC) is a lethal tumor, for which liver resection and transplantation are the only potentially curative treatments. No prospective, randomized study has compared survival in patients with compensated cirrhosis after the two operations Methods: Decision analysis modeling is an objective method to quantify risks and benefits. This study aimed to use decision analysis with a Markov model to estimate the impact of liver transplant and surgical resection on survival for patients wit [...]

Melanoma is a highly aggressive skin cancer with high incidence worldwide. There is growing evidence that aberrantly expressed non-coding RNAs (ncRNAs) play a role in the development, progression and dissemination of melanoma tumor cells. Among the many types of ncRNAs described in this review, the functions of micro- and long non-coding RNAs are described and related to the six hallmarks of cancer. Recently, ncRNAs discovered in body fluids have become known as one of the most promising groups of oncological bioma [...]

Studies have shown that decrease in time intubated is associated with better prognosis. Delirium is associated with increased duration of mechanical ventilation and Intensive Care Unit (ICU) length of stay. However, there is limited report on delirium in intubated seizure patients. As per report, low Glasgow Coma Scale (GCS) increased the risk of delirium and thus increasing ICU length of stay. Information on delirium and outcome in intubated seizure patients receiving lacosamide versus phenytoin is limited. Our re [...]

The modified Jade Wind-Barrier formula (MJWB) may prevent the common cold in the elderly with a Qi-deficiency Constitution. Previously, no controlled trial evidence existed to illuminate the concept of “preventive treatment of disease” as outlined in the constitution theory of Traditional Chinese Medicine. This theory distinctly suggests that enhancing the Qi-deficiency Constitution and modulating its functional state can prevent the occurrence of the common cold. This controlled trial (ClinicalTrials.gov identifie [...]
