New technology: Custom made implants, patient-specific alignment, and navigation - How to convince my hospital it's worth it: Current concepts.

Unicompartmental knee arthroplasty (UKA) faces significant challenges, including lower survival rates and higher revision rates than total knee arthroplasty (TKA). To address these issues, technological advancements like custom-made implants (CMI), patient-specific alignment (PSA), and computer-assisted systems (CAS) are being explored. These innovations aim to tailor procedures to individual joint morphology, soft tissue balance, and limb alignment, moving away from the traditional "one size fits all" approach.

Specific considerations in female patients with patellar instability: current concepts.

Prior literature suggests that patellofemoral instability (PFI) is significantly more prevalent in women than in men. This higher prevalence is commonly attributed to anatomical differences between sexes, particularly with patellofemoral alignment. These differences encompass a higher rate of trochlear dysplasia (TD), patella alta, an increased Q angle, and soft tissue imbalances.

Frequency of embryos appropriate for transfer following preimplantation genetic testing for monogenic disease.

Purpose: To identify specific likelihoods that an embryo will be classified as appropriate for transfer after preimplantation genetic testing for detection of a monogenic disorder (PGT-M), with or without preimplantation genetic testing for aneuploidy (PGT-A), separated by inheritance pattern.

Methods: Retrospective chart review of 181 selected PGT-M cycles performed at CooperGenomics in 2018 or 2019. For each cycle, the following main outcome data was collected: the number of embryos classified as affected with monogenic disease, the number detected to be chromosomally abnormal, the number that were recombinant, the number that had no result, and if applicable, the number which were aneuploid.

The Global Precipitation Measurement (GPM) mission's scientific achievements and societal contributions: reviewing four years of advanced rain and snow observations.

Precipitation represents a life-critical energy and hydrologic exchange between the Earth's atmosphere and its surface. As such, knowledge of where, when, and how much rain and snow falls is essential for scientific research and societal applications. Building on the 17-year success of the Tropical Rainfall Measurement Mission (TRMM), the Global Precipitation Measurement (GPM) Core Observatory (GPM-CO) is the first U.

Current concepts in cleft care: A multicenter analysis.

The current surgical techniques used in cleft repair are well established, but different centers use different approaches. To determine the best treatment for patients, a multi-center comparative study is required. In this study, we surveyed all craniofacial departments registered with the German Society of Maxillofacial Surgery to determine which cleft repair techniques are currently in use.

N-acetylcysteine crystals were coated with a formulation composing tripalmitin and polysorbate 65. The critical quality attributes (CQAs) were initially prioritized using failure mode and effects analysis.

Monitoring of a Hot Melt Coating Process via a Novel Multipoint Near-Infrared Spectrometer.

The aim of the present work was to develop a PAT strategy for the supervision of hot melt coating processes. Optical fibers were placed at various positions in the process chamber of a fluid bed device. Experiments were performed to determine the most suitable position for in-line process monitoring, taking into account such requirements as a good signal to noise ratio, the mitigation of dead zones, the ability to monitor the product over the entire process, and reproducibility.

Advanced lipid testing: when, why, and in whom?

Atherosclerotic cardiovascular disease is a leading cause of morbidity and mortality in developed countries. The management of blood cholesterol with the use of statin drugs in at-risk patients is a pillar of medical therapy for the primary and secondary prevention of cardiovascular disease. Although the standard lipid panel is adequate to accurately assess cardiovascular disease risk in most patients, there are some situations in which conventional cholesterol testing does not fully identify cardiovascular risk or reflect disease progression.

Process parameter screening studies are statistically planned under consideration of impacts on a potentially critical quality attribute, i.

Monitoring mammalian cell cultivations for monoclonal antibody production using near-infrared spectroscopy.

Near-infrared (NIR) spectroscopy as a process monitoring and process supervision technique is reviewed in the context of biomanufacturing.An industrial pilot-plant mammalian cell cultivation process has been chosen to illustrate the use of on-line in-situ NIR monitoring by means of an immersion transflectance NIR probe.NIR calibration development must be performed carefully and should incorporate a number of steps to obtain a properly validated model which exhibits long-term robustness and is independent of process scale.

Asymmetric dimethyl L-arginine (ADMA) is a critical regulator of myocardial reperfusion injury.

Objective: Endothelial dysfunction by the loss of nitric oxide (NO) is a critical event during reperfusion of ischemic myocardium. Reduced NO availability signals important pathophysiological changes leading to myocardial reperfusion injury. We have recently shown that NO biosynthesis can be disturbed by the endogenous NO synthase (NOS) inhibitor ADMA and that these changes are mediated by an impairment of its metabolism by dimethylarginine dimethylaminohydrolase (DDAH).

Effect of atorvastatin on peripheral endothelial function and systemic inflammatory markers in patients with stable coronary artery disease.

Background: Endothelial dysfunction, detectable by an impaired flow-mediated vasodilation (FMD) of the brachial artery, has been shown to be associated with increased levels of circulating proinflammatory markers. Therapeutic interventions such as lipid-lowering with statins increase FMD and decrease inflammatory markers, like soluble (s) E-selectin, soluble intercellular adhesion molecule-1 (sICAM-1) or high-sensitivity Creactive protein (hsCRP). The effect of atorvastatin therapy on both FMD and inflammatory markers in patients with stable coronary artery disease (CAD) has not been investigated.

Effect of atorvastatin on circulating proinflammatory T-lymphocyte subsets and soluble CD40 ligand in patients with stable coronary artery disease--a randomized, placebo-controlled study.

Background: Coronary atherosclerosis includes an activation of circulating T lymphocytes. Statins exert anti-inflammatory effects beyond lipid lowering. Whether these properties influence systemic T lymphocytes is unclear.

Countervailing effects of rapamycin (sirolimus) on nuclear factor-kappa B activities in neointimal and medial smooth muscle cells.

Objective: Local application of rapamycin (sirolimus) by drug-eluting stents prevents lumen obliteration after angioplasty by inhibition of neointimal hyperplasia. The effects of rapamycin on neointimal smooth muscle cells (niSMC) which are responsible for the occurrence of restenosis have not been investigated so far.

Methods And Results: Rat niSMC and medial SMC (mSMC) were obtained from balloon catheter-injured arteries.

Nestin-specific green fluorescent protein expression in embryonic stem cell-derived neural precursor cells used for transplantation.

Expression of the enhanced green fluorescent protein (EGFP) under control of a thymidine kinase promoter/nestin second intron was specifically detected in nestin immunoreactive neural precursor cells after selection of murine embryonic stem (ES) cells in chemically defined medium. Allowing differentiation in vitro, the capacity of these cells to give rise to astroglia, oligodendroglia, and neurones was investigated. After intracerebral transplantation, long-lasting integration of precursor cells into the host tissue was observed, serving as a pool for successive neuronal and glial differentiation.
