REVIEW
Helena Štorchová
The interactions between mitochondria and nucleus substantially influence plant development, stress response and morphological features. The prominent example of a mitochondrial-nuclear interaction is cytoplasmic male sterility (CMS), when plants produce aborted anthers or inviable pollen. The genes responsible for CMS are located in mitochondrial genome, but their expression is controlled by nuclear genes, called fertility restorers. Recent explosion of high-throughput sequencing methods enabled to study transcriptomic alterations in the level of non-coding RNAs under CMS biogenesis...

Kirsten E Gardner
Soon after the discovery of insulin in the early 1920s, the popular press celebrated the miraculous discovery. Although insulin had no curative effect on the chronic state of diabetes, it was frequently heralded as a "cure." This paper examines how the discovery of insulin intersected with the rise of diabetic technology and the transfer of medical technology to the home setting. By analyzing diabetic manuals written for patients and physicians, letters exchanged between patient and physician, medical journals, magazines and newspapers, I trace how patients learned about insulin and more significantly how patients adopted measurement technologies designed to allow better home administration of insulin...

BACKGROUND: The Lives Saved Tool (LiST) estimates the effects of maternal and child health interventions on mortality rates and the number of deaths. The family planning module in Spectrum interacts with LiST by providing estimates of the effects of scaling up family planning use on the number of live births, miscarriages, abortions, and stillbirths. METHODS: We use the proximate determinants of fertility framework to estimate the effects of changes in contraceptive use, proportion married, postpartum insusceptibility, abortion and sterility on the total fertility rate...

In this paper we describe the use of Cu-mediated [(18) F]fluorodeboronation for the automated production of PET radiotracers suitable for clinical use. Two recurrent issues with the method, low radiochemical conversion (RCC) on automation and protoarene byproduct purification issues, have been successfully addressed. The new method was utilized to produce sterile injectable doses of [(18) F]-(±)-IPMICF17, a PET radiotracer for tropomyosin receptor kinase B/C, using an automated synthesis module. Product was isolated in 1...

A 32-year-old woman, who presented for laparoscopic sterilization after two full-term normal deliveries, was incidentally diagnosed to have a left-sided complex cyst in the pouch of Douglas (POD). She had no history of previous surgeries or any symptoms of lower abdominal pain, nausea, or vomiting in the past. She underwent laparoscopy, and the left ovary and distal portion of the fallopian tube were absent in their normal position. An ectopic left ovary with dermoid cyst was noted in the POD. The right ovary and tube were in their normal position...

PURPOSE: Minor hand surgeries can be done under field sterility in procedure rooms. Surgeons are still sceptical about the usage of wide awake local anaesthesia no tourniquet (WALANT) technique. They perceive that patients can tolerate tourniquet for a brief period while they perform minor surgeries under local anaesthesia (LA). We compared the perceived comfort experienced by patients during minor hand surgeries with WALANT and LA/tourniquet. We investigated the difference in preoperative preparation time, operating time and blood loss between the two groups...

Inflammation is a reaction of the host to infectious or sterile stimuli and has the physiological purpose of restoring tissue homeostasis. However, uncontrolled or unresolved inflammation can lead to tissue damage, giving rise to a plethora of chronic inflammatory diseases, including metabolic syndrome and autoimmunity pathologies with eventual loss of organ function. Beta-nitrostyrene and its derivatives are known to have several biological activities, including anti-edema, vasorelaxant, antiplatelet, anti-inflammatory, and anticancer...

To conceal criminal activity of a bioterrorist or agroterrorist, the site of pathogen generation is often treated with sterilants to kill the organisms and remove evidence. As dead organisms cannot be analyzed by culture, this study examined whether DNA from sterilant-treated Bacillus cereus spores was viable for amplification. The spores were exposed to five common sterilants: bleach, Sterilox®, oxidizer foam (L-Gel), a peroxyacid (Actril®), and formaldehyde vapor. The spores were inoculated on typical surfaces found in offices and laboratories to test for environmental effects...

Transmission of bacteria from inanimate surfaces in healthcare associated environments is an important source of hospital acquired infections. A number of commercially available medical devices promise to fulfill antibacterial activity to reduce environmental contamination. In this study we developed a touch transfer assay modeling fingerprint transmission to investigate the antibacterial activity of surfaces, with confirmed antibacterial activity by a modified ISO 22196 (JIS Z 2801) assay to test such surfaces under more realistic conditions...

Given the importance of microbiology results on patient care, high quality standards are expected. Internal quality assurance (IQA) could mitigate the limitations of internal quality control, competency assessment and external quality assurance, adding a longitudinal insight, including pre- and post-analytical steps. Here, we implemented an IQA program in our clinical microbiology facilities with blind resubmission of routine samples during 22 months. One-hundred-and-twenty-one out of 123 (98.4%) serological analyses and 112 out of 122 (91...

Despite the numerous bacteria detection and elimination techniques available nowadays, sensitive diagnosis and treatment of sepsis (caused by the presence of bacteria in the bloodstream), especially at the early stage, remain big challenges. Here we report a nanosystem for early sepsis diagnosis and complete extracorporeal blood disinfection, based on iron oxide magnetic nanoparticles functionalized with chlorin e6 molecules and bacterial species-identifiable aptamers (Fe3O4-Ce6-Apt). We demonstrate that the Fe3O4-Ce6-Apt nanosystem can achieve simultaneous blood bacterial species identification and enrichment in a single step, and the enriched bacteria can be easily detected with the assistance of fluorescence microscopic determination...

Asher D Cutter
Speciation genetics research in diverse organisms shows the X-chromosome to be exceptional in how it contributes to 'rules' of speciation. Until recently, however, the nematode phylum has been nearly silent on this issue, despite the model organism Caenorhabditis elegans having touched most other topics in biology. Studies of speciation with Caenorhabditis accelerated with the recent discovery of species pairs showing partial inter-fertility. The resulting genetic analyses of reproductive isolation in nematodes demonstrate key roles for the X-chromosome in hybrid male sterility and inviability, opening up new understanding of the genetic causes of Haldane's rule, Darwin's corollary to Haldane's rule, and enabling tests of the large-X effect hypothesis...

Floral scents are key mediators of biotic interactions between flowers and various organisms such as pollinators, antagonistic animals and bacteria. It has been shown that emissions of floral volatiles are influenced by interactions with other organisms at the levels of roots, leaves and flowers. However, it is largely unknown whether and how epiphytic bacteria associated with flowers affect the composition of floral scent. By comparing volatiles of sterile and inoculated plants we found that bacteria may add components, induce or reduce the emission of compounds, and potentially catabolize others...

The formation of fertile male gametophyte is known to require timely degeneration of polyfunctional tapetum tissue. The last process caused by the programmed cell death (PCD) is a part of the anther program maturation which leads to sequential anther tissue destruction coordinated with pollen differentiation. In the present work, distribution of abscisic acid (ABA) and indole-3-acetic acid (IAA) in developing anthers of male-fertile and male-sterile lines of petunia (Petunia hybrida L.) was analyzed by using the immunohistochemical method...
