Four saponins, obtained in good yield were evaluated for their anti-inflammatory activities in a rat model using the carrageenan-induced paw edema protocol. Two of these exhibited significant anti-inflammatory activities demonstrated through inhibition of the paw edema by 64 and 60%. Dendritic cell (DC) populations are the orchestrators of immune responses and arise from hematopoietic progenitors. Studies to unravel DC ontogeny have been conducted mainly in mice due to historical and practical reasons. However, understanding DC development in humans is a prerequisite for manipulating this process for therapeutic design. Here, we review the advantages and limitations of methods used to study human DC development in vitro and in vivo. In particular, we examine the in vitro culture systems that support the differentiation of all or some DC subpopulations. We also review recent discoveries regarding human DC precursors and factors that regulate their differentiation. As the most abundant microbes in the atmosphere, airborne bacteria are closely involved in affecting human health, regional climate and ecological balance. The mobility of airborne microorganisms makes it necessary to study the community dynamic in short cycle. Nevertheless, it remains obscure how the airborne bacteria especially the pathogenic bacteria vary on the small time scale of day and night. To investigate the nycterohemeral discrepancy of airborne total bacteria and pathogenic bacteria, PM2.5 samples were collected in Hangzhou between day and night. Microbial taxonomic information was obtained through 16S rRNA gene sequencing and "human pathogens database" screening. Further analyses based on Multiple Regression Matrices (MRM) approach and Concentration Weighted Trajectory (CWT) model were conducted to elucidate the effect of local environmental factors and long-range transport. The community composition of total bacteria tended to be similar in the daytime while pathogenic bacteria turned out to be homogeneous in the nighttime. To be vigilant, the diversity of airborne pathogenic bacteria echoed the frequency of anthropogenic activities with the pathogen inhalation rate roughly at 428 copies/h and 235 copies/h respectively in daytime and nighttime. The nycterohemeral discrepancy of total bacteria was principally driven by the filtering of environmental factors, i.e., CO and NO2, indicating that anthropogenic activities brought about the homogeneity. Airborne pathogenic bacteria coupled with the strong resistances of environmental filtering stood out from their non-pathogenic counterpart, which enabled the long-range transport. Indeed, the nycterohemeral discrepancy of pathogenic bacteria was shaped by the transport of air masses. This research filled the gaps in temporal variance of airborne microorganisms on the small time scale of day and night, providing crucial foundation for precisely predicting ecological and health effects of bioaerosols. In a lake basin, there is a mismatch between river and lake water quality targets and a method for setting specific water quality targets for these rivers is urgently needed. Using Dianchi Lake as an example, we proposed a lake basin water quality management system based on the river-lake water quality response relationship, coupled with a Soil and Water Assessment Tool (SWAT) basin hydrological model and Environmental Fluid Dynamics Code (EFDC) lake water quality hydrodynamic model. River water quality control requirements based on the river-lake water quality response were proposed, under the premise that the Dianchi Lake water quality reaches the required standard. Then, water quality control targets for rivers were determined, and corrected for influencing factors, such as current river water quality and composition of flow. Our systematic approach efficiently identified key lake basin pollution sources, and accurately located key points for water quality improvement and pollution control. Combined with a correction for clean water source and current water quality of each river, the proposed water quality targets were practical and operable. Meanwhile, the EFDC model was used to verify the entire process to ensure that river water quality targets could be set to achieve lake water quality targets. To ensure that Dianchi Lake water quality can reach Class IV standard, the Chemical oxygen demand (COD) concentration would need to be maintained under 30 mg/L,Waihai total nitrogen (TN) below 7 mg/L, total phosphorus (TP) below 0.2 mg/L, and ammonia nitrogen (NH3-N) below 2 mg/L. Mobile communication devices (MCDs), including cell phones and smart phones, have become an essential part of everyday life. Despite their frequent usage, most people, even healthcare personnel, often ignore the possibility that these devices might accumulate to carry a variety of microbial flora during and after the inspection of patients. The handling of MCDs with unwashed hands and/or their seldom cleaning can aggravate potential health risks. Many of the harbored bacteria species can be harmful to immune-suppressed patients for whom the disinfection precautions should be taken more seriously. In this review, we discuss the significance of maintaining the cleanliness of mobile devices, especially in healthcare settings, to prevent the spread of nosocomial infections in patients. Furthermore, we discuss strategies to address microbial contamination of MCDs to maintain good hand hygiene for the users of smartphones or other mobile communication devices. These techniques are capable of providing instant disinfection of the devices along with residual effects over prolonged periods. BACKGROUND There is an increasing incidence of cardiovascular diseases in Africa. Nurses' ability to undertake cardiopulmonary resuscitation (CPR) can significantly impact the survival of patients who experience cardiac arrest. OBJECTIVES We aimed to identify the effects of CPR training among Registered Nurse-Bachelor of Science in Nursing (RN-BSN) students in Mozambique. DESIGN A one-group pretest-posttest repeated-measures quasi-experimental design. SETTING Auditorium of a general hospital and 2 Anne manikins, but no automatic external defibrillator. PARTICIPANTS Thirty-two RN-BSN students. METHODS Students' attitudes and self-efficacy on CPR were measured by self-reported questionnaires three times (before, immediately after, and 20 weeks post intervention). Data were analyzed by the paired t-test and repeated-measures analysis of variance. RESULTS Attitude and self-efficacy scores of students on CPR significantly increased immediately after CPR training, but decreased 20 weeks after the intervention (p  less then  .001). Sociodemographic characteristics did not significantly differ throughout the measurements of attitude or self-efficacy. CONCLUSIONS CPR manikin training positively affected attitude and self-efficacy in CPR among RN-BSN nursing students immediately, but not at 20 weeks, after the training. There is a need for research to repeatedly quantify parameters in a controlled study at different intervals and develop an instructor-training course customized to Mozambique. BACKGROUND It is important for nurses to provide safe, high-quality care for patients, and clinical experiences allow nursing students to integrate theory into practice. However, many students have anxiety about clinical rotations. OBJECTIVES The concerns of nursing students about clinical experiences and factors relating to self-efficacy in a rural Bachelor of Science in Nursing (BSN) program were examined. DESIGN This was a mixed-methods study, and students were surveyed prior to and at the end of their clinical experiences. SETTING The study location is a public liberal arts university in the rural, southeast United States. PARTICIPANTS Junior level students (first and second semester) and senior level students (first and second semester) levels of BSN students participated in this project. RESULTS Qualitative themes were identified, including concerns regarding clinical competence, expectations of learning, aspects of patient/peer/instructor interactions, as well as learning strategies and preferences. The student's level of confidence regarding communication to patients and physicians, assessment of heart and lung sounds, interview skills, documentation, and discussion of nursing procedures increased significantly from pre to post-survey. Confidence levels in physical assessment skills rose significantly after the clinical experience (t' = -6.3718 with 140 df, p  less then  .001). CONCLUSION Strategies that nurse educators can use prior to, during, and after the clinical experience to address student concerns about clinical experiences include the use of caring, competent clinical instructors, orientation to clinical sites, laboratory and simulation days, self-reflection, peer-support, and debriefing. Many neurological disorders are associated with excessive and/or uncontrolled cursing. The right prefrontal cortex has long been implicated in a diverse range of cognitive processes that underlie the propensity for cursing, including non-propositional language representation, emotion regulation, theory of mind, and affective arousal. Neurogenic cursing often poses significant negative social consequences, and there is no known behavioral intervention for this communicative disorder. We examined whether right vs. left lateralized prefrontal neurostimultion via tDCS could modulate taboo word production in neurotypical adults. We employed a pre/post design with a bilateral frontal electrode montage. Half the participants received left anodal and right cathodal stimulation; the remainder received the opposite polarity stimulation at the same anatomical loci. We employed physiological (pupillometry) and behavioral (reaction time) dependent measures as participants read aloud taboo and non-taboo words. Pupillary responses demonstrated a crossover reaction, suggestive of modulation of phasic arousal during cursing. Participants in the right anodal condition showed elevated pupil responses for taboo words post stimulation. In contrast, participants in the right cathodal condition showed relative dampening of pupil responses for taboo words post stimulation. We observed no effects of stimulation on response times. We interpret these findings as supporting modulation of right hemisphere affective arousal that disproportionately impacts taboo word processing. We discuss alternate accounts of the data and future applications to neurological disorders. SAG (Sensitive to Apoptosis Gene), also known as RBX2 or ROC2, is a RING component of CRL (Cullin-RING ligase), required for its activity. Our previous studies showed that Sag/Rbx2 co-operated with Kras or Pten loss to promote tumorigenesis in the lung and prostate, respectively, but antagonized Kras to inhibit skin tumorigenesis, suggesting a tissue/context dependent function of Sag. NSC 663284 The role of SAG in KRAS-induced pancreatic tumorigenesis is unknown. In this study, we mined a cancer database and found that SAG is overexpressed in pancreatic cancer tissues and correlates with decreased patient survival. Whether Sag overexpression plays a causal role in pancreatic tumorigenesis is unknown. Here, we reported the generation of Sag transgenic mouse model alone (CS), or in combination with KrasG12D, driven by p48-Cre (KCS mice) for pancreatic specific Sag expression. Sag transgenic expression alone has no phenotypical abnormality, but in combination with KrasG12D promotes ADM (acinar-to-ductal metaplasia) conversion in vitro and mPanIN1 formation in vivo at the early stage, and impairs pancreatic functions at the late stage, as evidenced by poor glucose tolerance and significantly reduced α-Amylase activity, and induction of cytogenesis and acinar cell loss, eventually leading to atrophic pancreata and shortened mouse life-span.
