However, plants have evolved adaptive mechanisms to respond to the harmful effects of drought. They reprogram their transcriptome, proteome, and metabolome that alter their cellular and physiological processes and establish cellular homeostasis. One of the crucial regulatory processes that govern this reprogramming is post-transcriptional regulation by microRNAs (miRNAs). miRNAs are small non-coding RNAs, involved in the downregulation of the target mRNA via translation inhibition/mRNA degradation/miRNA-mediated mRNA decay/ribosome drop off/DNA methylation. Many drought-inducible miRNAs have been identified and characterized in plants. Their main targets are regulatory genes that influence growth, development, osmotic stress tolerance, antioxidant defense, phytohormone-mediated signaling, and delayed senescence during drought stress. Overexpression of drought-responsive miRNAs (Osa-miR535, miR160, miR408, Osa-miR393, Osa-miR319, and Gma-miR394) in certain plants has led to tolerance against drought stress indicating their vital role in stress mitigation. Similarly, knock down (miR166/miR398c) or deletion (miR169 and miR827) of miRNAs has also resulted in tolerance to drought stress. Likewise, engineered Arabidopsis plants with miR165, miR166 using short tandem target mimic strategy, exhibited drought tolerance. Since miRNAs regulate the expression of an array of drought-responsive genes, they can act as prospective targets for genetic manipulations to enhance drought tolerance in crops and achieve sustainable agriculture. Further investigations toward functional characterization of diverse miRNAs, and understanding stress-responses regulated by these miRNAs and their utilization in biotechnological applications is highly recommended.
Recurrent hepatocellular carcinoma (HCC) patients with microvascular invasion (MVI)-positive primary tumor is at high risk of re-recurrence while treated with radiofrequency ablation (RFA). We aimed to investigate whether neoadjuvant conventional transarterial chemoembolization (cTACE) was effective in reducing re-recurrence after RFA for recurrent HCC patients with MVI-positive primary tumors.
In this retrospective multicenter study, 468 patients with solitary small recurrent HCC (≤3.0cm) underwent RFA alone (
 = 322) or with neoadjuvant cTACE (
 = 146) between June 2007 and December 2017 were included. Overall survival (OS) and recurrence-free survival (RFS) were compared.
The 1-, 5-year OS rates were 74.8%, 42.5% for RFA with neoadjuvant cTACE group, and 53.5%, 28.7% for RFA group (
 < 0.001). The corresponding RFS rates were 51.7%, 24.4% for RFA with neoadjuvant cTACE group, and 36.1%, 9.3% for RFA group (
 < 0.001). In subgroup analyses, the OS and RFS for neoadjuvant cTACE group were lonfrequency ablation (RFA) achieved better efficacy.Multivariable analyses showed that the interval of recurrence from initial treatment > 1 year and RFA alone were independent prognostic factors of overall survival and recurrence-free survival, respectively.
1 year and RFA alone were independent prognostic factors of overall survival and recurrence-free survival, respectively.Irreversible electroporation (IRE) ablation is gaining popularity over the last decade as a nonthermal alternative to thermal ablation technologies such as radiofrequency ablation (RFA) and Microwave ablation (MWA). This review serves as a practical guide for applying IRE to colorectal cancer liver metastases (CRLM) for interventional radiologists, oncologists, surgeons, and anesthesiologists. It covers patient selection, procedural technique, anesthesia, imaging, and outcomes.
Cardiac sarcoidosis (CS) is the cardiac, and occasionally the only manifestation, of a systemic disease of unknown etiology inherently challenging to definitively diagnose due to the lack of a reliable gold standard, the current being endomyocardial biopsy, the yield of which is low owing to the patchy nature of involvement. Societal guidelines employ specific criteria to make a probabilistic diagnosis, integrating clinical assessment with conventional and advanced cardiac imaging.
This review begins with an introduction to CS, followed by a discussion of diagnostic guidelines commonly used, then delves into an in-depth review of the imaging modalities currently available to assess for CS. Particular attention is made to discussing findings, strengths, limitations, and future directions for each modality.
The burden of CS may be significantly larger than previously thought. With the low yield of endomyocardial biopsy, advanced cardiac imaging is increasingly employed to determine CS likelihood. Cardiac magnetic resonance is adept at detecting myocardial scar and able to differentiate between CS and other cardiomyopathies. F-18Fluorodeoxyglucose positron emission tomography is superior at detecting active disease (myocardial inflammation) which may be amenable to immunosuppressive treatment, as well as detecting extracardiac involvement and identifying potential biopsy sites.

These models are used to predict and control the outcome of hyperthermia (up to 45°C) treatments, and of thermal coagulation treatments at higher temperatures (>45°C). The validity and accuracy of the commonly used models (CEM43) are questionable when heating above the hyperthermia temperature range occurs, leading to an over-estimation of the accumulation of thermal damage. A new CEM43 dose model based on an Arrhenius-type, Vogel-Tammann-Fulcher, equation using published data, is introduced in this work. The new dose values for the same damage threshold that was produced at different in-vivo skin experiments were in the same order of magnitude, while the current dose values varied by two orders of magnitude. In addition, the dose values obtained using the new model for the same damage threshold in 6 lesions in ex-vivo liver experiments were more consistent than the current model dose values. The contribution of this work is to provide new modeling approaches to inform more robust thermal dosimetry for improved thermal therapy modeling, monitoring, and control.
We investigated if the addition of an inter-professional student-led medication review team (ISP-team) to standard care can increase the number of detected ADRs and reduce the number of ADRs 3months after an outpatient visit.
In this controlled clinical trial, patients were allocated to standard care (control group) or standard care plus the ISP team (intervention group). read more The ISP team consisted of medical and pharmacy students and student nurse practitioners. The team performed a structured medication review and adjusted medication to reduce the number of ADRs. Three months after the outpatient visit, a clinical pharmacologist who was blinded for allocation performed a follow-up telephone interview to determine whether patients experienced ADRs.
During the outpatient clinic visit, significantly more (p<0.001) ADRs were detected in the intervention group (n=48) than in the control group (n=10). In both groups, 60-63% of all detected ADRs were managed. Three months after the outpatient visit, significantly fewer (predominantly mild and moderately severe) ADRs related to benzodiazepine derivatives and antihypertensive causing dizziness were detected in the patients of the intervention group.
An ISP team in addition to standard care increases the detection and management of ADRs in elderly patients resulting in fewer mild and moderately severe ADRs.

This study compared prevalence and characteristics of headaches between pediatric patients with chronic kidney disease and pediatric patients with transplanted kidneys and identify factors associated with headaches in the entire cohort.
We interviewed 87 children and adolescents with either chronic kidney disease or transplanted kidney, regarding the prevalence of headaches and their characteristics. We reviewed hospital charts for medical history and blood test.
Twenty-two patients (25.3%) reported experiencing headaches, of them 15 (68%) had migraine. The prevalence was greater among those with chronic kidney disease than among those after kidney transplant 36.6% vs 15.2%,
 = .03. Headache, mostly migraine, was associated with lower glomerular filtration and higher phosphate level.
In a pediatric population, headaches were less prevalent among patients after kidney transplantation than among patients with chronic kidney disease. The lower headache rate after kidney transplantation may be related to improvement in homeostasis and electrolyte balance.

Venous sinus manometry performed by microcatheter to assess candidacy for venous sinus stenting in patients with idiopathic cranial pressure (IIH) can be tiring, time-consuming and unreliable. Pressure wire is widely used to measure coronary pressure and evaluate coronary stenosis severity, but venous sinus manometry using the pressure guide wire has only been reported in one case, and few studies have examined the accuracy of this approach.
To compare venous manometry performed by microcatheter with by pressure wire under awake setting in patients with IIH.
The manometry results of 30 patients with IIH were recorded by Rebar-27 microcatheter and a pressure wire under awake setting. The mean venous pressures (MVPs) and trans-stenosis pressure gradients were obtained and compared between microcatheter and pressure wire. Paired t-test) were used to evaluate the data between the two groups.
MVPs in superior sagittal sinus (SSS) and torcula were slightly higher with microcatheter, though without statistically significant differences (p > 0.05). MVPs in transverse sinus (TS) and sigmoid sinus (SS) were significantly higher with microcatheter (p < 0.05). Trans-stenotic pressure gradient with microcatheter was significantly higher than with pressure wire (p＜0.001).
Intracranial venous pressure measured with the microcatheter and pressure wire showed a moderate difference. Compared with the traditional microcatheter method，the pressure wire is safe, fast and effective method to identify the patient needing intervention.
