REVIEW
A Kordzadeh, M O Liu, N V Jayanthi
INTRODUCTION: The aim of this systematic review is to establish the clinical impact of open (mesh and/or without mesh) and laparoscopic hernia repair (transabdominal pre-peritoneal (TAP) and/or totally extra-peritoneal (TEP)) on male fertility. The incidence of male infertility following various types of inguinal hernia repair is currently unknown. The lack of high-quality evidence has led to various speculations, suggestions and reliance on anecdotal experience in the clinical practice...

Various gastrointestinal (GI) factors affect drug and formulation behavior after oral administration, including GI transfer, motility, pH and GI fluid volume and composition. An in-depth understanding of these physiological and anatomical variables is critical for a continued progress in oral drug development. In this review, different methodologies (invasive versus non-invasive) to explore the impact of physiological variables on formulation behavior in the human GI tract are presented, revealing their strengths and limitations...

The periodontitis-associated pathogen Treponema denticola is a spirochetal bacterium that swims by rotating its cell body like a corkscrew using periplasmic flagella. We compared physiologic and pathogenic properties, including motility, in four strains of T. denticola. Phase-contrast microscopy showed differential motility between the strains; ATCC 35404 showed the highest motility, followed by ATCC 33521, and the remaining two strains (ATCC 35405 and ATCC 33520) showed the lowest motility. Transmission electron microscopy showed that the low motility strains exhibited extracellular flagellar protrusions resulting from elongated flagella...

The gastro-intestinal peptide ghrelin has been assigned many functions. These include appetite regulation, energy metabolism, glucose homeostasis, intestinal motility, anxiety, memory or neuroprotection. In the last decade, this pleiotropic peptide has been proposed as a therapeutic agent in gastroparesis for diabetes and in cachexia for cancer. Ghrelin and its receptor, which is expressed throughout the brain, play an important role in motivation and reward. Ghrelin finely modulates the mesencephalic dopaminergic signaling and is thus currently studied in pathological conditions including dopamine-related disorders...

Formation of motile cilia in vertebrate embryos is essential for proper development and tissue function. Key regulators of motile ciliogenesis are the transcription factors FOXJ1 and NOTO, which are conserved throughout vertebrates. Downstream target genes of FOXJ1 have been identified in a variety of species, organs and cultured cell lines; in murine embryonic and foetal tissues, however, FOXJ1 and NOTO effectors have not been comprehensively analysed and our knowledge of the downstream genetic programme driving motile ciliogenesis in the mammalian lung and ventral node is fragmentary...

Dysphagia in elderly patients has a major effect on nutrition and quality of life (QOL). Although several studies have shown that aging itself is associated with changes in esophageal motility, the impact of these changes on dysphagia symptoms and QOL is unknown. This study assessed the manometric diagnoses of elderly patients with dysphagia compared with diagnoses in younger counterparts. Participants included 116 consecutive patients examined for dysphagia from 2007 to 2014. We divided patients into three groups by age: Group A, 66 years and older (24 men, 23 women); Group B, 45-65 years (18 men, 24 women); and Group C, 44 years and younger (15 men, 12 women)...

Successful fertilization in flowering plants depends on the precise directional growth control of pollen tube through the female pistil tissue, towards the female gametophyte contained in the ovule for delivery of non-motile sperm cells. Cysteine-rich peptides LUREs secreted from the synergid cells on either side of the egg cell act as ovular attractants of pollen tubes. Competency control by the pistil is crucial for the response of pollen tubes to these ovular attractants. We recently reported that ovular 4-O-methyl-glucuronosyl arabinogalactan AMOR induces competency of the pollen tube to respond to ovular attractant LURE peptides in Torenia fournieri...

Metastasis, initially driven by cells migrating and invading through the local environment, leads to most cancer-associated deaths. Cells can use a variety of modes to move in vitro, all of which depend on Rho GTPases at some level. While traditionally it was thought that Rac1 activity drives protrusive lamellipodia at the leading edge of a polarised cell while RhoA drives rear retraction, more recent work in 3D microenvironments has revealed a much more complicated picture of GTPase dynamics. In particular, RhoA activity can dominate the leading edge polymerisation of actin to form filopodial actin-spike protrusions that drive more invasive cell migration...

Type IV pili are hair-like bacterial surface appendages that play a role in diverse processes such as cellular adhesion, colonization, twitching motility, biofilm formation, and horizontal gene transfer. These extracellular fibers are composed exclusively or primarily of many copies of one or more pilin proteins, tightly packed in a helix so that the highly hydrophobic amino-terminus of the pilin is buried in the pilus core. Type IV pili have been characterized extensively in Gram-negative bacteria, and recent advances in high-throughput genomic sequencing have revealed that they are also widespread in Gram-positive bacteria...

BACKGROUND: Phosphoprotein phosphatase 1 catalytic subunit gamma 2 (PPP1CC2), a PPP1CC tissue-specific alternative splice restricted to testicular germ cells and spermatozoa, is essential for spermatogenesis and spermatozoa motility. The key to understand PPP1CC2 regulation lies on the characterization of its interacting partners. METHODS: We construct a testis/sperm-enriched protein interaction network and analyzed the topological properties and biological context of the network...

BACKGROUND: Pterygium, a growth of the conjunctiva over the cornea, is a progressive disease leading in advanced stages to visual impairment, restriction of ocular motility, chronic inflammation and cosmetic concerns. Surgical removal is the treatment of choice, but recurrence can be a problem. Currently the best surgical option in terms of recurrence is conjunctival autograft. To date the most common surgical methods of attaching conjunctival autografts to the sclera are through suturing or fibrin glue...

Experimental evolution of the plant pathogen Ralstonia solanacearum, where bacteria were maintained on plant lineages for more than 300 generations, revealed that several independent single mutations in the efpR gene from populations propagated on beans were associated with fitness gain on bean. In the present work, novel allelic efpR variants were isolated from populations propagated on other plant species, thus suggesting that mutations in efpR were not solely associated to a fitness gain on bean, but also on additional hosts...

A major roadblock to understanding how microbes in the gastrointestinal tract colonize and influence the physiology of their hosts is our inability to genetically manipulate new bacterial species and experimentally assess the function of their genes. We describe the application of population-based genomic sequencing after chemical mutagenesis to map bacterial genes responsible for motility in Exiguobacterium acetylicum, a representative intestinal Firmicutes bacterium that is intractable to molecular genetic manipulation...

Matricellular proteins play multiple roles in primary tumor growth, local invasion and tumor angiogenesis. However, their contribution to metastasis and the putative mechanisms involved are less well characterized. In ER-negative human breast cancer, elevated expression levels of the matricellular protein Cysteine-rich angiogenic inducer 61 (CYR61) are associated with more aggressive progression. Here, we investigated the role of CYR61 in breast cancer lung metastasis using the triple negative human breast cancer cell lines MDA-MB-231 and SUM159...

Time-lapse, deep-tissue imaging made possible by advances in intravital microscopy has demonstrated the importance of tumour cell migration through confining tracks in vivo. These tracks may either be endogenous features of tissues or be created by tumour or tumour-associated cells. Importantly, migration mechanisms through confining microenvironments are not predicted by 2D migration assays. Engineered in vitro models have been used to delineate the mechanisms of cell motility through confining spaces encountered in vivo...

: The neuropeptide calcitonin gene-related peptide (CGRP) is a key player in migraine. While migraine can be treated using CGRP antagonists that act peripherally, the relevant sites of CGRP action remain unknown. To address the role of CGRP both within and outside the central nervous system, we used CGRP-induced light aversive behavior in mice as a measure of migraine-associated photophobia. Peripheral (intraperitoneal, IP) injection of CGRP resulted in light aversive behavior in wild-type CD1 mice similar to aversion previously seen following central (intracerebroventricular, ICV) injection...
