Pectin methylesterase inhibitor gene family in the seven Rosaceae species (including three pear cultivars) is characterized and three pectin methylesterase inhibitor genes are identified to regulate pollen tube growth in pear. Pectin methylesterase inhibitor (PMEI) participates in a variety of biological processes in plants. However, the information and function of PMEI genes in Rosaceae are largely unknown. In this study, a total of 423 PMEI genes are identified in the genomes of seven Rosaceae species. The PMEI genes in pear are categorized into five subfamilies based on structural analysis and evolutionary analysis. WGD and TD are the main duplication events in the PMEI gene family of pear. Quantitative real-time PCR analysis indicates that PbrPMEI23, PbrPMEI39, and PbrPMEI41 are increasingly expressed during pear pollen tube growth. Under the treatment of recombinant proteins PbrPMEI23, PbrPMEI39 or PbrPMEI41, the content of methylesterified pectin at the region 5-20μm from the pollen tube tip significaing pear pollen tube growth. Under the treatment of recombinant proteins PbrPMEI23, PbrPMEI39 or PbrPMEI41, the content of methylesterified pectin at the region 5-20 μm from the pollen tube tip significantly increases, and the growth of pear pollen tubes is promoted. These results indicate that PMEI regulates the growth of pollen tubes by changing the distribution of methylesterified pectin in the apex.
To incorporate novel findings on pathophysiology and treatment of posttransplant hypertension.

(1) The sodium retaining effects of CNIs are mediated by stimulation of the thiazide-sensitive sodium chloride co-transporter in the distal convoluted tubule and in this regard chlorthalidone was proven to be an effective antihypertensive drug in renal transplantation. (2) Local and not systemic activation of the renin-angiotensin-aldosterone system plays a crucial role in the pathogenesis of posttransplant hypertension. (3) Recent randomized controlled trials failed to prove the presumed superiority of renin-angiotensin blockers in kidney transplantation. (4) Steroid-free and mammalian target of rapamycin-based immunosuppressive drug combinations did not show favorable effects on blood pressure control. (5) In a recent report the risk of non-melanoma skin cancer was higher with thiazide diuretics. But the increased cancer risk in transplant recipients is mainly attributed to comorbidities, such as diabetes and ngiotensin blockers in kidney transplantation.

(5) In a recent report the risk of non-melanoma skin cancer was higher with thiazide diuretics. But the increased cancer risk in transplant recipients is mainly attributed to comorbidities, such as diabetes and hypertension and of course to the transplantation condition itself or the obligatory application of immunosuppression, and has little to do with the antihypertensive medication Actual recommendations about BP targets in adult renal transplant recipients are coming from a post hoc analysis of a large randomized trial with another primary endpoint. Unless convincing studies on treatment of hypertension after renal transplantation are available, the ESC/ESH Guidelines 2018 should apply for these patients.
Chronic pain continues to present a large burden to the US healthcare system. Neuropathic pain, a common class of chronic pain, remains particularly difficult to treat despite extensive research efforts. Current pharmacologic regimens exert limited efficacy and wide, potentially dangerous side effect profiles. This review provides a comprehensive, preclinical evaluation of the literature regarding the role of flavonoids in the treatment of neuropathic pain.

Flavonoids are naturally occurring compounds, found in plants and various dietary sources, which may have potential benefit in neuropathic pain. Numerous animal-model studies have demonstrated this benefit, including reversal of hyperalgesia and allodynia. Flavonoids have also exhibited an anti-inflammatory effect relevant to neuropathic pain, as evidenced by the reduction in multiple pro-inflammatory mediators, such as TNF-α, NF-κB, IL-1β, and IL-6. Flavonoids represent a potentially new treatment modality for neuropathic pain in preclinical models, though human clinical evidence is yet to be explored at this time.

Metastatic lesions to the appendix are rare. They usually present with acute appendicitis or remain asymptomatic and are diagnosed incidentally. Metastases to the appendix have been reported from a number of primary tumor sites including ovary, colon, gastric and lung. We report a laparoscopic appendectomy for a metachronous metastatic lesion to the appendix from the uterine cervix.

A 68-year-old woman, who underwent radical hysterectomy for cervical cancer 16years previously, presented with nausea and gradually worsening right lower quadrant abdominal pain. Abdominal computed tomography scan showed an enlarged appendix and periappendiceal fat stranding. She was diagnosed with appendicitis and underwent laparoscopic appendectomy. Pathological findings showed adenocarcinoma in the submucosa and muscularis propria. Gastrointestinal endoscopy and positron emission tomography with computed tomography (PET-CT) did not show other lesions. Immunohistochemical analysis showed cytokeratin 7 (CK7) positive, cytokeratin 20 (CK20) negative, estrogen receptor (ER) 70-80% and progesterone receptor (PgR) 40-50%. The ER and PgR expression was similar to the cervical lesion 16years previously, and the diagnosis was a metastatic lesion to the appendix from the uterine cervix.

Metastasis to the appendix from cancer of the uterine cervix is a rare lesion.

Drug development has evolved over the years from being one-at-a-time to be massive screens in an industrial manner. Bringing a new therapeutic agent from concept to bedside can take a decade and cost billions of dollars-with most concepts failing along the way. Of the few compounds that make it to clinical testing, less than one out of eight make it to approval. This traditional drug development pipeline is challenging for prevalent diseases and makes the development of new therapeutics for rare diseases financially intractable.

Repurposing of drugs is an alternative to identify new applications for the thousands of compounds that have already been approved for clinical use. There is now a range of strategies for such efforts that leverage clinical data, pharmacologic data, and/or genomic or transcriptomic data. These strategies, together with examples, are detailed in this review. Drug repurposing bypasses the pre-clinical work and thereby opens up the opportunity to provide targeted treatment at a fractle drug development channel.
To review the current knowledge on interactions between dietary factors and microRNAs (miRNAs) in essential hypertension (EH) pathogenesis.

There exists an integration of maintenance signals generated by genetic, epigenetic, immune, and environmental (e.g., dietary) factors that work to sustain balance in the gut-liver axis. It is well established that an imbalance in this complex, intertwined system substantially increases the risk for EH. As such, pertinent research has been taken to decipher how each signal operates in isolation and together in EH progression. Recent literature indicates that both macro- and micronutrients interrupt regulatory miRNA expressions and thus, alter multiple cellular processes that contribute to EH and its comorbidities. We highlight how carbohydrates, lipids, proteins, salt, and potassium modify miRNA signatures during EH. The disruption in miRNA expression can negatively impact communication systems such as over activating the renin-angiotensin-aldosterone system, modulatirates, lipids, proteins, salt, and potassium modify miRNA signatures during EH. The disruption in miRNA expression can negatively impact communication systems such as over activating the renin-angiotensin-aldosterone system, modulating the vascular smooth muscle cell phenotype, and promoting angiogenesis to favor EH. We also delineate the prognostic value of miRNAs in EH and discuss the pros and cons of surgical vs dietary prophylactic approaches in EH prevention. We propose that dietary-dependent perturbation of the miRNA profile is one mechanism within the gut-liver axis that dictates EH development.
In this review, we summarize the major known cardiac toxicities of common chemotherapeutic agents and the role of nuclear cardiac imaging for the surveillance and assessment of cancer therapeutics-related cardiac dysfunction in routine clinical practice.

Cardiotoxicity from chemotherapy causes a significant mortality and limits potentially life-saving treatment in cancer patients. Close monitoring of cardiac function during chemotherapy is an accepted method for reducing these adverse effects especially in patients with cancer therapeutics-related cardiac dysfunction. Nuclear imaging is a sensitive, specific, and highly reproducible modality for assessment of cardiac function. Nuclear imaging techniques including equilibrium radio nucleotide angiography, myocardial perfusion imaging, and novel experimental molecular imaging are the various objective tools available in addition to conventional echocardiography and cardiac magnetic resonance imaging in the surveillance, assessment, and follow-up of cancer therapeutics-related cardiac dysfunction.

The review addresses the role of exercise in triggering ventricular arrhythmias and promoting disease progression in arrhythmogenic cardiomyopathy (AC) patients and gene-mutation carriers, the differential diagnosis between AC and athlete's heart and current recommendations on exercise activity in AC.

AC is an inherited heart muscle disease caused by genetically defective cell-to-cell adhesion structures (mainly desmosomes). The pathophysiological hallmark of the disease is progressive myocyte loss and replacement by fibro-fatty tissue, which creates the substrates for ventricular arrhythmias. Animal and human studies demonstrated that intense exercise, but not moderate physical activity, may increase disease penetrance, worsen the phenotype, and favor life-threatening ventricular arrhythmias. It has been proposed that in some individuals prolonged endurance sports activity may in itself cause AC (so-called exercise-induced AC). see more The studies agree that intense physical activity should be avoided in patients with AC and healthy gene-mutation carriers.
