Scheduled intravenous ketorolac is safe and reduces narcotic use after robotic-assisted simple prostatectomy.

We sought to examine whether scheduled intravenous (IV) ketorolac decreased post-operative narcotic utilization and changed peri-operative outcomes (including complications) in patients undergoing robotic-assisted simple prostatectomy (RASP). An IRB-approved, retrospective chart review was performed of all patients undergoing RASP at a single institution from November 2017 to July 2019. Patient demographic, peri-operative, and post-operative data, including morphine equivalent use (MEU), were collected.

Perinephric fat stranding is associated with increased age and stone size but not with serum creatinine in patients with obstructing ureterolithiasis.

Previous reports show increased severity of perinephric fat stranding (PFS) with elevated serum creatinine in obstructing ureterolithiasis. We sought to investigate this association with our institution's patient population.We reviewed charts of patients diagnosed with obstructive ureterolithiasis or nephrolithiasis in our emergency department between January and October 2018.

Alterations in the brain serotonin system and serotonin-regulated behavior during aging in zebrafish males and females.

The brain serotonin (5-HT) system performs a neurotrophic function and supports the plasticity of the nervous system, while its age-related changes can increase the risk of senile neurodegeneration. Zebrafish brain is highly resistant to damage and neurodegeneration due to its high regeneration potential and it is a promising model object in searching for molecular factors preventing age-related neurodegeneration. In the present study alterations in 5-HT-related behavior in the home tank and the novel tank diving test, as well as 5-HT, 5-HIAA levels, tryptophan hydroxylase (TPH), monoamine oxidase (MAO) activity and the expression of genes encoding TPH, MAO, 5-HT transporter and 5-HT receptors in the brain of 6, 12, 24 and 36 month old zebrafish males and females are investigated.

A Solitary Stalled 80S Ribosome Prevents mRNA Recruitment to Stress Granules.

In response to stress stimuli, eukaryotic cells typically suppress protein synthesis. This leads to the release of mRNAs from polysomes, their condensation with RNA-binding proteins, and the formation of non-membrane-bound cytoplasmic compartments called stress granules (SGs). SGs contain 40S but generally lack 60S ribosomal subunits.

Effect of Prolonged Exposure to Short Daylight and a Tryptophan Hydroxylase Inhibitor on the Behavior and Brain Serotonin System in Danio rerio.

Long-Term Continuous Computer Registration and Analysis of Motor Activity of a Group of Zebrafish Danio rerio.

A new algorithm for long-term continuous computer recording and analysis of motor activity of a group of zebrafish in the home tank has been developed. The movements of a group of Danio rerio during the entire light period and for several days are recorded at a frequency of 1 frame/sec in the form of short (15 min) files. Then these files are analyzed by the unique DanioStudo software, which, using a threshold algorithm and appropriate masks, calculates for each frame the sum of pixels associated with fish (the sum of fish silhouettes), and for two consecutive frames, the sum of altered pixels (the sum of altered fish silhouettes).

Needle Aligned Ultrasound Image-Guided Access Through Dual-Segment Array.

Unlabelled: Ultrasound (US) guided access for percutaneous nephrolithotomy (PCNL) is gaining popularity in the urology community as it reduces radiation risk. The most popular technique involves manual image-needle alignment. A misaligned needle however needs to be retracted and reinserted, resulting in a lengthened operation time and complications such as bleeding.

Ex-vivo ureteroscopy, laser lithotripsy, and stone basketing extraction of deceased donor kidney stones during machine perfusion preservation.

The incidence of nephrolithiasis in kidney donors is rare. The timing and treatment of nephrolithiasis in deceased donor kidneys are not well established. While some programs have proposed ex-situ rigid or flexible ureteroscopy treatment before transplantation, we report on two cases of kidney stones in the same deceased donor that we treated by flexible ureteroscopy and laser lithotripsy performed during the storage time on a hypothermic perfusion machine.

Single-domain antibody delivery using an mRNA platform protects against lethal doses of botulinum neurotoxin A.

Single-domain antibodies (sdAbs, VHHs, or nanobodies) are a promising tool for the treatment of both infectious and somatic diseases. Their small size greatly simplifies any genetic engineering manipulations. Such antibodies have the ability to bind hard-to-reach antigenic epitopes through long parts of the variable chains, the third complementarity-determining regions (CDR3s).

Age-Related Alterations in the Level and Metabolism of Serotonin in the Brain of Males and Females of Annual Turquoise Killifish ().

The annual turquoise killifish () is a laboratory model organism for neuroscience of aging. In the present study, we investigated for the first time the levels of serotonin and its main metabolite, 5-hydroxyindoleacetic acid, as well as the activities of the key enzymes of its synthesis, tryptophan hydroxylases, and degradation, monoamine oxidase, in the brains of 2-, 4- and 7-month-old male and female . The marked effect of age on the body mass and the level of serotonin, as well as the activities of tryptophan hydroxylases and monoamine oxidase in the brain of killifish were revealed.

Polyribosomes of circular topology are prevalent in mammalian cells.

Polyribosomes, the groups of ribosomes simultaneously translating a single mRNA molecule, are very common in both, prokaryotic and eukaryotic cells. Even in early EM studies, polyribosomes have been shown to possess various spatial conformations, including a ring-shaped configuration which was considered to be functionally important. However, a recent in situ cryo-ET analysis of predominant regular inter-ribosome contacts did not confirm the abundance of ring-shaped polyribosomes in a cell cytoplasm.

Effect of Short Photoperiod on the Behavior and Brain Serotonin System in Zebrafish Danio rerio.

Reduced daylight duration causes the development of seasonal affective disorder (SAD; depression-like disorders characterized by depressed mood, apathy, bulimia, and weight gain) in sensitive individuals. Neurotransmitter serotonin (5-HT) is involved in the mechanism of SAD. Zebrafish (D.

Efficacy of Intramuscular Ketorolac for Preventing Renal Colic Post Stent Removal: Randomized Controlled Trial.

Purpose: The treatment of stones ureteroscopically is associated with postoperative pain, thought to be due largely to the use of ureteral stents. In some, stent removal precipitates renal colic that can last from minutes to hours. We sought to determine if intramuscular ketorolac could reduce post-stent removal renal colic.

Non-Canonical Translation Initiation Mechanisms Employed by Eukaryotic Viral mRNAs.

Viruses exploit the translation machinery of an infected cell to synthesize their proteins. Therefore, viral mRNAs have to compete for ribosomes and translation factors with cellular mRNAs. To succeed, eukaryotic viruses adopt multiple strategies.

Accessing Mitochondrial Protein Import in Living Cells by Protein Microinjection.

Mitochondrial protein biogenesis relies almost exclusively on the expression of nuclear-encoded polypeptides. The current model postulates that most of these proteins have to be delivered to their final mitochondrial destination after their synthesis in the cytoplasm. However, the knowledge of this process remains limited due to the absence of proper experimental real-time approaches to study mitochondria in their native cellular environment.
