Morpholines are common heterocycles in pharmaceutical and agricultural products, yet methods to synthesize them from 1,2-amino alcohols are inefficient. We report the simple, high yielding, one or two-step, redox neutral protocol using inexpensive reagents (ethylene sulfate and BuOK) for the conversion of 1,2-amino alcohols to morpholines. Key to this methodology is the identification of general conditions that allow for the clean isolation of monoalkylation products derived from a simple S2 reaction between an amine and ethylene sulfate.

While the importance of spiritual care in nursing is widely recognized, there is often a gap in understanding nurses' willingness to provide such care. This cross-sectional study aimed to explore the association between self-efficacy, spiritual well-being, and willingness to provide spiritual care among nursing staff.

The purpose of this study was to evaluate the value of diffusion-weighted magnetic resonance imaging (DW-MRI) as a reliable tool to assess salivary gland function in NPC patients after radiotherapy.
Materials And Methods: This study analysed the MR images of 31 NPC patients at different time points within 2-3 years after radiotherapy.
The synthesis of di- and trisubstituted vinyl fluorides with high isomeric purity remains a challenge for organic synthesis. While many methods exist to access these compounds, the separation of the desired isomer from the minor isomer and/or starting materials often is difficult. Herein, we report a practical method to access di- and trisubstituted vinyl fluorides via a selective Horner-Wadsworth-Emmons olefination/hydrolysis, which provides crystalline 2-fluoroacrylic acids in high (>98%) -isomeric purity.

In this study, we investigated the characteristics of Cr(VI) bioreduction and biosorption by an MTB isolate, Magnetospirillum gryphiswaldense MSR-1, which has a higher growth rate and wider reflexivity in culture conditions. Our results demonstrated that the MSR-1 strain could remove Cr(VI) up to the concentration of 40 mg L and with an optimal activity at neutral pH conditions.

A healthy dietary pattern (DP) plays an important role in regulating glycolipid metabolism, while evidence about DP on ADT-related metabolic abnormalities is still controversial. To explore the effect of DP on metabolic outcomes in PCa patients with ADT, PubMed, Embase, Cochrane, and CINAHL were searched from inception to 10 September 2022.

Peplau, who is known as "the mother of psychiatric society," developed an interpersonal relationship theory for nursing. Implementation of this theory in practice has been shown to positively impact patients' quality of life and reduce adverse symptoms after surgery.

Methods: A total of 68 subjects form neonatal intensive care unit were randomly assigned into control group (n=20), premature infant oral motor intervention (PIOMI) group (n=25) and premature infant oral motor intervention with breast milk (BM-PIOMI) group (n=23).
Results: BM-PIOMI group had significant shorter initiation of oral feeding (IOF) time compared to PIOMI group (2.
This study aimed to explore the effectiveness of an inpatient hospice palliative care unit (PCU) and palliative consultation service (PCS) on comprehensive quality of life outcome (CoQoLo) among terminally ill cancer patients. This was a prospective longitudinal study. Terminally ill cancer patients who met the inclusion criteria and received PCU or PCS in a northern Taiwanese medical center were recruited.

Background: Fever clinic is the first line of defence against the epidemic during COVID-19 in China.
Methods: Our study combines the Delphi method and the analytic hierarchy process.
Background: Wheat is one of the most widely planted crops worldwide. The heading date is important for wheat environmental adaptability, as it not only controls flowering time but also determines the yield component in terms of grain number per spike.
Results: In this research, homozygous genotypes with early and late heading dates derived from backcrossed progeny were selected to conduct RNA-Seq analysis at the double ridge stage (W2.

Using path modeling, this study aimed to explore whether mental adjustment was directly or indirectly related to comprehensive quality of life outcome (CoQoLO) among patients with terminal cancer. We conducted a cross-sectional designed study among patients with terminal cancer who underwent convenience sampling at our northern Taiwan clinic from August 2019 to August 2020. Patient characteristics data were collected via structured questionnaires, namely, the Mini-Mental Adjustment to Cancer Scale and the Comprehensive Quality of Life Outcome Inventory.

The transcription factor retinoic acid receptor-related orphan nuclear receptor γt (RORγt) is important for the activation and differentiation of Th17 cells and thus is an attractive pharmacologic target for the treatment of Th17-mediated diseases. A novel series of pyrazinone RORγ antagonists was discovered through hybridization of two distinct screening hits and scaffold hopping.
