Continuous Flow Synthesis of Copper Oxide Nanoparticles Enabling Rapid Screening of Synthesis-Structure-Property Relationships.

An adjustable and scalable method for the continuous flow synthesis of cupric oxide nanoparticles (CuO NPs), targetted the reduction of their activity to synthetic biomembranes to inform the fabrication of nanoparticles (NPs) with reduced toxicity for commercial applications. By manipulating key factors; temperature, residence time, and the ratio of precursor to reductant, precise control over the morphology of CuO NPs is achieved with X-ray diffraction (XRD) and transmission electron microscopy (TEM) confirming the formation of needle-shaped CuO NPs. One-variable-at-a-time studies reveal a relationship between the synthesis conditions and the characteristics of the resultant NPs, with CuO NPs varying controllably between 10-50 nanometres in length and 4-10 nanometres in width.

Microscopic ferning in human pre-ejaculate is highly correlated with the absence of sperm.

Objective: We characterize microscopic ferning in pre-ejaculate samples with and without sperm.

Study Design: Healthy, male, withdrawal-experienced participants provided up to three paired pre-ejaculate and ejaculate samples. We centrifuged ejaculate samples to obtain a supernatant without sperm.

TIPE2 gene transfer ameliorates aging-associated osteoarthritis in a progeria mouse model by reducing inflammation and cellular senescence.

Osteoarthritis (OA) pain is often associated with the expression of tumor necrosis factor alpha (TNF-α), suggesting that TNF-α is one of the main contributing factors that cause inflammation, pain, and OA pathology. Thus, inhibition of TNF-α could potentially improve OA symptoms and slow disease progression. Anti-TNF-α treatments with antibodies, however, require multiple treatments and cannot entirely block TNF-α.

Murine Progeria Model Exhibits Delayed Fracture Healing with Dysregulated Local Immune Response.

Background: Bone fracture is one of the most globally prevalent injuries, with an estimated 189 million bone fractures occurring annually. Delayed union or nonunion occurs in up to 15% of fractures and involves the interruption or complete failure of bone continuity following fracture. Preclinical testing is essential to support the translation of novel strategies to promote improved fracture repair treatment, but there is a paucity of small animal models that recapitulate clinical attributes associated with delayed fracture healing.

β-catenin mRNA encapsulated in SM-102 lipid nanoparticles enhances bone formation in a murine tibia fracture repair model.

Fractures continue to be a global economic burden as there are currently no osteoanabolic drugs approved to accelerate fracture healing. In this study, we aimed to develop an osteoanabolic therapy which activates the Wnt/β-catenin pathway, a molecular driver of endochondral ossification. We hypothesize that using an mRNA-based therapeutic encoding β-catenin could promote cartilage to bone transformation formation by activating the canonical Wnt signaling pathway in chondrocytes.

How Do Women Vote: What Women Post About Home Birth Versus Hospital Birth on Popular Social Media Platforms.

Introduction: The rates of home birth have been increasing; reliance on social media as a source of medical advice and support for patients has also been increasing. This is the first study that directly evaluates birthing people's perceptions, attitudes, and advice about planned home births expressed in public posts and comments on two popular social media platforms - Reddit and TikTok.

Methods: Posts on each platform were searched from January 2017 through July 2022 using the terms "home birth" and "home vs.

Mineral coated microparticles doped with fluoride and complexed with mRNA prolong transfection in fracture healing.

Impaired fracture healing, specifically non-union, has been found to occur up to 14% in tibial shaft fractures. The current standard of care to treat non-union often requires additional surgeries which can result in long recovery times. Injectable-based therapies to accelerate fracture healing have the potential to mitigate the need for additional surgeries.

Five years later: Can women in Los Angeles County, California, get adequate pill supplies?

Objectives: This study sought to determine if pharmacies in Los Angeles County had implemented 2017 legislation requiring insurance companies based in California to fully reimburse for 13 cycles of oral contraceptives dispensed at once.

Study Design: We conducted a secret shopper telephone survey of Los Angeles County pharmacies nearly 5 years after the legislation went into effect. We chose the categorical state family program (Family PACT) to represent all programs covered by the legislation.

Drospirenone and estetrol: evaluation of a newly approved novel oral contraceptive.

Introduction: Estetrol (E4) is a native estrogen produced only by the fetal liver during pregnancy. E4 is the first new estrogen to be used in hormonal contraception since the introduction of oral contraceptives in 1960. Ethinyl estradiol, the most commonly used estrogen in oral contraceptives today, increases the risks of thromboembolism and has other significant hepatic impacts, which induce important drug-drug interactions.

Revitalizing the infection prevention workforce with a fellowship program for underrepresented groups.

Infection preventionist (IP) positions are difficult to fill, and future workforce shortages are anticipated. The IP field has less racial and ethnic diversity than the general nursing workforce or patient population. A targeted fellowship program for underrepresented groups allowed the recruitment and training of IPs while avoiding staffing shortages.

Fisetin Attenuates Cellular Senescence Accumulation During Culture Expansion of Human Adipose-Derived Stem Cells.

Mesenchymal stem cells (MSCs) have long been viewed as a promising therapeutic for musculoskeletal repair. However, regulatory concerns including tumorgenicity, inconsistencies in preparation techniques, donor-to-donor variability, and the accumulation of senescence during culture expansion have hindered the clinical application of MSCs. Senescence is a driving mechanism for MSC dysfunction with advancing age.

Satisfaction with a Segesterone Acetate and Ethinyl Estradiol Contraceptive Vaginal System Among Recent Oral Contraceptive or Hormonal Contraceptive Vaginal Ring Users.

We evaluated satisfaction with use of a segesterone acetate and ethinyl estradiol (0.15/0.013 mg) contraceptive vaginal system (CVS) among women who had recently used a monthly contraceptive vaginal ring or contraceptive pills.

The Senolytic Drug Fisetin Attenuates Bone Degeneration in the Progeria Mouse Model.

Aging leads to several geriatric conditions including osteoporosis (OP) and associated frailty syndrome. Treatments for these conditions are limited and none target fundamental drivers of pathology, and thus identifying strategies to delay progressive loss of tissue homeostasis and functional reserve will significantly improve quality of life in elderly individuals. A fundamental property of aging is the accumulation of senescent cells.

The effects of fisetin on bone and cartilage: A systematic review.

As the worldwide population progresses in age, there is an increasing need for effective treatments for age-associated musculoskeletal conditions such as osteoporosis and osteoarthritis (OA). Fisetin, a natural flavonoid, has garnered attention as a promising pharmaceutical option for treating or delaying the progression of osteoporosis and OA. However, there is no systematic review of the effects of fisetin on bone and cartilage.

Therapeutic approaches to activate the canonical Wnt pathway for bone regeneration.

Activation of the canonical Wingless-related integration site (Wnt) pathway has been shown to increase bone formation and therefore has therapeutic potential for use in orthopedic conditions. However, attempts at developing an effective strategy to achieve Wnt activation has been met with several challenges. The inherent hydrophobicity of Wnt ligands makes isolating and purifying the protein difficult.

Continuation rates of two different-sized copper intrauterine devices among nulliparous women: Interim 12-month results of a single-blind, randomised, multicentre trial.

Background: The most widely used copper intrauterine device (IUD) in the world (the TCu380A), and the only product available in many countries, causes side effects and early removals for many users. These problems are exacerbated in nulliparous women, who have smaller uterine cavities compared to parous women. We compared first-year continuation rates and reasons/probabilities for early removal of the TCu380A versus a smaller Belgian copper IUD among nulliparous users.

Avoidance of mild threat observed in generalized anxiety disorder (GAD) using eye tracking.

Attentional biases towards threat are assumed to be a causal factor in the development of anxiety disorders, including generalized anxiety disorder (GAD). However, findings have been inconsistent, and studies often examine single time-point bias during threat exposure, instead of across time. Attention to threat may shift throughout exposure (e.
