Nanoemulsions containing plant oils: How do they influence hair treatment?

Cosmetic and dermatological products, mainly the hair treatments, are projected to have remarkable growing in coming years. Nanotechnology, specifically nanoemulsions, has potential to be used in several hair products, owing to their beneficial properties. Concurrently, plant‐derived cosmetics have become more popular over the years to consumers who prefer a safer, natural and sustainable approach. There is a lack of studies combining plant oils and nanotechnology for haircare formulations. In this work, different plant oil‐loaded nanoemulsions were prepared to investigate the influence of their particle size, zeta potential and composition on hair treatment efficacy.
Genotyping of PCV3 based on reassembled viral gene sequences

Abstract Porcine circovirus type 3 (PCV3) has been reported in many countries such as USA, China, Korea and many European countries during 2015–2018. The six PCV3 strains named IH, SJ, N5, N10, N13 and N62 were detected out of 220 samples by PCR methods while the prevalence our study was conducted in 2017 to 2018. The six detected strains were hard to genotype with reference viruses due to their diverse phylogenetic relationship. PCV3 capsid, ORF3 and replicase protein coding genes were reassembled at the nucleotide sequence level, then 16 new reassembled PCV3 sequences were generated. Based on the maximum likelihood mapping analysis of 303 PCV3 sequences a model with a combination of replicase, ORF3 and capsid protein coding genes was selected as the most appropriate target for genotyping, which provided the best support for the clade classification into three genotypes and several subtypes (genotype 1, genotype 2; subtype: a and b, genotype 3; subtype a, b, c, d, e, f, g, h). This study, the IH_Korea_2017 and N62_Korea_2018 strains belong to genogroup 3 (subtype a) the SJ_Korea_2017 strain genogroup 3 (subtype g) and the N5, N10, N13 Korea_ 2018 strains genogroup 3 (subtype f), respectively. In conclusion, this study may provide insights to classification of PCV3 genotypes around the world.
Serotonergic Innervations of the Orbitofrontal and Medial-prefrontal Cortices are Differentially Involved in Visual Discrimination and Reversal Learning in Rats

Abstract Cross-species studies have identified an evolutionarily conserved role for serotonin in flexible behavior including reversal learning. The aim of the current study was to investigate the contribution of serotonin within the orbitofrontal cortex (OFC) and medial prefrontal cortex (mPFC) to visual discrimination and reversal learning. Male Lister Hooded rats were trained to discriminate between a rewarded (A+) and a nonrewarded (B−) visual stimulus to receive sucrose rewards in touchscreen operant chambers. Serotonin was depleted using surgical infusions of 5,7-dihydroxytryptamine (5,7-DHT), either globally by intracebroventricular (i.c.v.) infusions or locally by microinfusions into the OFC or mPFC. Rats that received i.c. v. infusions of 5,7-DHT before initial training were significantly impaired during both visual discrimination and subsequent reversal learning during which the stimulus–reward contingencies were changed (A− vs. B+). Local serotonin depletion from the OFC impaired reversal learning without affecting initial discrimination. After mPFC depletion, rats were unimpaired during reversal learning but slower to respond at the stimuli during all the stages; the mPFC group was also slower to learn during discrimination than the OFC group. These findings extend our understanding of serotonin in cognitive flexibility by revealing differential effects within two subregions of the prefrontal cortex in visual discrimination and reversal learning.
Therapeutic Alliance Between Bereaved Parents and Physicians in the PICU.

OBJECTIVES Therapeutic alliance is the collaborative bond that develops between patients/families and healthcare providers. Our objective is to determine the extent of therapeutic alliance bereaved parents perceive to have occurred with their child's physicians during their child's PICU stay, and associated factors. DESIGN Multicenter observational study. SETTING Eight children's hospitals affiliated with the Collaborative Pediatric Critical Care Research Network. PATIENTS Parents greater than or equal to 18 years old whose child died in a PICU (including cardiac ICU). INTERVENTIONS Bereaved parents completed the Human Connection Scale, a 16-item measure of therapeutic alliance, 6 months after their child's death. Human Connection Scale scores range from 16 to 64 with higher scores indicating greater alliance. Parents provided sociodemographic data, and medical records were reviewed for the child's clinical characteristics. MEASUREMENTS AND MAIN RESULTS Two-hundred and thirty-three parents of 157 deceased children responded to the Human Connection Scale with greater than or equal to 80% item completion. Among parents, 146 (62.7%) were female, 155 (66.5%) were White and 46 (19.7%) were Black, 175 (75.1%) were married, and 209 (89.7%) had at least a high-school education. Among children, median age at the time of death was 5.9 years (interquartile range, 0.64-13.9 yr) and 114 (72.6%) died after limitation or withdrawal of life support. Mean Human Connection Scale score was 51.4 ± 11.1 for all parents, 52.6 ± 9.0 for White parents, and 47.0 ± 13.7 for Black parents. In multivariable modeling predicting Human Connection Scale scores, race was the only parent or child characteristic in the final model. Human Connection Scale scores were significantly different (-4.56; 95% CI, -8.53 to -0.6; p = 0.025) between the Black and White parents with items about trust, care, and honest communication showing the greatest mean difference. CONCLUSIONS Among parents bereaved in the PICU, therapeutic alliance with physicians is moderately high. Future research should identify strategies to strengthen therapeutic alliance with Black parents and examine the role of alliance on bereaved parents' health outcomes.
Role of the Kisspeptin/KISS1 Receptor System in the Testicular Development of Mice.

BACKGROUND Kisspeptin and its receptor KISS1R have been found to be essential regulators of reproductive function. Previous data have revealed the presence of Kiss1 and Kiss1r mRNAs in the hypothalamus and the testis of humans and rodents. However, the precise location and possible physiological role of the kisspeptin/KISS1R system in the testis remain ambiguous. METHODS We first produced an anti-KISS1R immunoglobulin Y antibody for KISS1R identification. To detect the exact sites of KISS1R and kisspeptin expression in the testis, we conducted immunohistochemistry assays on sections of testes. We used real-time polymerase chain reactions (PCR) to identify Kiss1r in mice and to determine the expression levels of testicular genes. Finally, to verify the upstream regulation on the Kisspeptin/KISS1 receptor system, we treated primary mouse Leydig cells and MA-10 cells with luteinizing hormone (LH) and Br-cAMP, respectively and examined Kiss1 and Kiss1r mRNA expression. RESULTS Immunohistochemistry assays revealed that kisspeptin was expressed in Leydig cells and KISS1R was localized in the seminiferous tubules. With real-time PCR, we found Kiss1r mRNA was constitutively expressed in the mouse testis from birth until the postnatal fourth week. Furthermore, mRNA expression of Kiss1 was synchronized with that of Insl3 and Cyp19a. However, the expression of the LH receptor-encoding gene increased 1 week earlier than did Kiss1 expression. This indicated that the kisspeptin/KISS1R system in the testis may be controlled by LH and cAMP signaling pathways. Finally, we confirmed that Kiss1 mRNA expression was increased in both LH-treated primary Leydig cells and Br-cAMP-treated MA-10 cells (p < 0.05). On the other hand, cotreatment of both cell lines with Br-cAMP and a protein kinase A inhibitor RP-cAMP significantly suppressed 50% of Br-cAMP-induced Kiss1 expression (p < 0.05). CONCLUSION We discovered that Kiss1 expression in mouse Leydig cells was induced by LH through the cAMP/PKA pathway. Based on the presence of kisspeptin receptors on spermatids, we inferred that kisspeptin and development-related factors have synergistic effects on spermatogenesis. Nevertheless, more studies are required to elaborate the role of the kisspeptin/KISS1R system in testicular development.
Elevated miR‐124‐3p in the aging colon disrupts mucus barrier and increases susceptibility to colitis by targeting T‐synthase

The risk of colitis and colorectal cancer increases markedly throughout adult life, endangering the health and lives of elderly individuals. Previous studies have proposed that bacterial translocation and infection are the main risk factors for these diseases. Therefore, in the present study, we aimed to identify the underlying mechanism by focusing on the mucus barrier function and mucin‐type O‐glycosylation. We evaluated alterations in the colon mucus layer in 2‐, 16‐, and 24‐month‐old mice and aged humans. Aged colons showed defective intestinal mucosal barrier and changed mucus properties. The miR‐124‐3p expression level was significantly increased in the aged distal colonic mucosa, which was accompanied by an increase in pathogens and bacterial translocation. Meanwhile, T‐synthase, the rate‐limiting enzyme in O‐glycosylation, displayed an age‐related decline in protein expression. Further experiments indicated that miR‐124‐3p modulated O‐glycosylation by directly targeting T‐synthase. Moreover, young mice overexpressing miR‐124‐3p exhibited abnormal glycosylation, early‐onset, and more severe colitis. These data suggest that miR‐124‐3p predisposes to senile colitis by reducing T‐synthase, and the miR‐124‐3p/T‐synthase/O‐glycans axis plays an essential role in maintaining the physiochemical properties of colonic mucus and intestinal homeostasis.
Intralesional immunotherapy for molluscum contagiosum: A review

Molluscum contagiosum (MC) is a common cutaneous viral infection with no standard treatment. The virus responsible for MC is thought to be cleared by cell mediated immunity (CMI). Intralesional immunotherapy that stimulates CMI has been shown to be an effective treatment for other cutaneous viruses. In this review, we evaluate the efficacy and safety of intralesional immunotherapy in the treatment of MC. Articles met inclusion criteria if they examined the effects of intralesional immunotherapy as a treatment for MC, with a clear outcome and reproducible methodology. 228 studies were screened and 10 studies met criteria for inclusion. Intralesional immunotherapies investigated included candida, combined measles, mumps, rubella vaccine, tuberculin purified protein derivative, vitamin D3, interferon α, and Streptococcal substrain OK‐432. Studies demonstrated clearance of MC lesions following intralesional immunotherapy, with complete response rates between 36% and 100%. No serious adverse effects were noted. Intralesional immunotherapy is a safe and effective treatment option for MC in pediatric and adult patients.
Accurately Assessing Gay Men’s Erectile Functioning: A Critique of the International Index of Erectile Function (IIEF) Use with Gay Men

ABSTRACT The International Index of Erectile Functioning (IIEF) has been widely used to measure gay men’s erectile functioning. However, the IIEF was initially developed using a sample of men whose sexual orientation was unspecified. Using scales not validated for specific populations can result in inaccurate assessments. The purpose of the current study was to evaluate the dimensionality, reliability, and validity of the IIEF with a large sample of gay men. One thousand and eighteen men self-identifying as “exclusively gay” completed an online survey consisting of demographics, the IIEF, the Hospital Anxiety and Depression Scale (HADS), the Perceived Stress Scale 4 (PSS4), and the Gay Male Sexual Difficulties (GMSD) erectile difficulties sub-scale. The replicability of the IIEF factor structure with a gay male sample was determined using exploratory and confirmatory factor analyses. Additionally, the HADS, PSS4, and GMSD were used to determine the validity of the IIEF. The current study was unable to replicate the IIEF factor structure. Four items required deletion and the factor solution differed from the original. Thus, reinterpretation of the latent variables was deemed necessary. Although the resultant 12-item IIEF evidenced model fit, validity, and reliability, it is not recommended for use with gay men. The revised IIEF is unable to accurately measure gay men’s erectile functioning as the content of the items fail to capture their sexual behaviors (i.e., insertive and receptive anal sex).
Proximity Ligation Assay for Detecting Protein‐Protein Interactions and Protein Modifications in Cells and Tissues in Situ

Biochemical methods can reveal stable protein‐protein interactions occurring within cells, but the ability to observe transient events and to visualize the subcellular localization of protein‐protein interactions in cells and tissues in situ provides important additional information. The Proximity Ligation Assay® (PLA) offers the opportunity to visualize the subcellular location of such interactions at endogenous protein levels, provided that the probes that recognize the target proteins are within 40 nm. This sensitive technique not only elucidates protein‐protein interactions, but also can reveal post‐translational protein modifications. The technique is useful even in cases where material is limited, such as when paraffin‐embedded clinical specimens are the only available material, as well as after experimental intervention in 2D and 3D model systems. Here we describe the basic protocol for using the commercially available Proximity Ligation Assay™ materials (Sigma‐Aldrich, St. Louis, MO), and incorporate details to aid the researcher in successfully performing the experiments. © 2020 Wiley Periodicals LLC.
Evaluation of postoperative analgesia in pediatric patients after hip surgery: lumbar plexus versus caudal epidural analgesia

Background:There continues to be focus on the value of regional and neuraxial anesthetic techniques when combined with general anesthesia to improve postoperative analgesia. The reported advantages include decreased postoperative opioid requirements, decreased medication-related adverse effects, decreased hospital length of stay, and increased patient satisfaction. Orthopedic procedures of the hip may be amenable to such techniques as there is significant postoperative pain with the requirement for hospital admission and the administration of parenteral opioids. Given the surgical site, various regional anesthetic techniques may be used to provide analgesia including caudal epidural anesthesia (CEA) or lumbar plexus blockade (LPB). Purpose: The objective of this study was to assess the effectiveness of LPB versus CEA as an analgesic thechnique for patients undergoing elective hip surgery from the opioid consumption and pain scores perspective. Patients and methods: The current study retrospectively reviews our experience with CEA and LPB for postoperative analgesia after hip surgery in the pediatric population. Regional anesthesia technique was reviewed as well as opioid requirements and pain scores. Results: The study cohort included 61 patients, 29 who received an LPB and 32 who received CEA. No difference was noted in the demographics between the two groups. Intraoperative opioid use was 0.7 (IQR: 0.5, 1.1) mg/kg of oral morphine equivalents (MEs) in the LPB group compared to 0.6 (IQR: 0.5, 0.9) in the CEA group (p=0.479). Postoperative opioid use over the first 48 hrs was 4 (IQR: 1, 6) mg/kg of oral ME in the LPB group, compared to 2 (interquartile range [IQR]: 1, 3) in the CEA group (p=0.103). Over the first 24 hrs after surgery, the median pain score in the LPB group was 5 (IQR: 1–6), compared to 3 (IQR: 0, 5) in the CEA group (p=0.014). Conclusion: These retrospective data suggest a modest postoperative benefit of CEA when compared to LPB following hip surgery in the pediatric population. Postoperative pain scores were lower in patients receiving CEA; however, no difference in the intraoperative or postoperative opioid requirements was noted between the two groups.
Vascular Disease Patient Information Page: COVID–19-related thrombosis

SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) is the virus responsible for coronavirus disease 2019 (COVID-19). As of October 1, 2020, SARS-CoV-2 has infected over 34 million people and has resulted in over 1 million deaths worldwide. In the United States alone, there are over 7 million confirmed cases and greater than 200,000 deaths.1 Elderly individuals and those with chronic medical conditions are at the highest risk, but the disease can strike people in good health and those in any age group, and it may be carried and transmitted to others by people with no symptoms. SARS-CoV-2 is now well known to cause lung disease, including pneumonia or more severe respiratory complications. COVID-19 is spread mostly through exhaled air and respiratory droplets. Wearing masks protects those around us from contracting SARS-CoV-2 and may protect the wearer from getting another person’s infection. Pneumonia-related COVID-19 has gained the most attention, as patients with severe illness frequently have low blood oxygen levels and may require mechanical ventilation (i.e. life support with a ‘breathing machine’), often for prolonged periods of time. But COVID-19 can affect multiple organs in the body beyond the lungs, such as the heart, gastrointestinal tract, kidneys, bone marrow, liver, and skin.2 The reason so many body systems are affected by COVID-19 may be due to the fact that SARS-CoV-2 infects a wide variety of human cells, including the cells that make up the surface of our blood vessels that supply circulation to these organs, called ‘the endothelium’.
Functional connectivity during language processing in 3‐month‐old infants at familial risk for autism spectrum disorder

Auditory statistical learning (ASL) plays a role in language development and may lay a foundation for later social communication impairment. As part of a longitudinal study of infant siblings, we asked whether electroencephalography (EEG) measures of connectivity during ASL at 3 months of age‐differentiated infants who showed signs of autism spectrum disorder (ASD) at age 18 months. We measured spectral power and phase coherence in the theta (4–6 Hz) and alpha (6–12 Hz) frequency bands within putative language networks. Infants were divided into ASD‐concern (n = 14) and No‐ASD‐concern (n = 49) outcome groups based on their ASD symptoms at 18 months, measured using the Autism Diagnostic Observation Scale Toddler Module. Using permutation testing, we identified a trend toward reduced left fronto‐central phase coherence at the electrode pair F9‐C3 in both theta and alpha frequency bands in infants who later showed ASD symptoms at 18 months. Across outcome groups, alpha coherence at 3 months correlated with greater word production at 18 months on the MacArthur‐Bates Communicative Development Inventory. This study introduces signal processing and analytic tools that account for the challenges inherent in infant EEG studies, such as short duration of recordings, considerable movement artifact, and variable volume conduction. Our results indicate that connectivity, as measured by phase coherence during 2.5 min of ASL, can be quantified as early as 3 months and suggest that early alternations in connectivity may serve as markers of resilience for neurodevelopmental impairments.
Programmed death-1 or programmed death ligand-1 inhibitors? A meta-analysis of differential efficacy as compared to chemotherapy in advanced non-small cell lung cancer

Background Programmed Death-1 (PD-1) and Programmed Death Ligand-1 (PDL-1) inhibitors have improved survival over chemotherapy in advanced Non- Small Cell Lung Cancer (NSCLC). However, it is unclear if there are class specific differences in the efficacy of Checkpoint Inhibitors (CPIs) in NSCLC, and this paper is designed to answer these clinical questions. Methods For this Meta-analysis, we searched PubMed, Science of Web, “Clinicaltrials.gov” and online sources for trials comparing PD-1 and PDL-1 CPIs in advanced NSCLC. The data for Hazard Ratio (HR) and their Confidence Intervals (CI) for Overall Survival (OS) was extracted. Results A sum of 9739 patients from 16 trials were included in the efficacy evaluation. For the OS endpoint, both PD-1 inhibitors (HR = 0.76, 95%CI = 0.69–0.83, P < 0.001) and PDL-1 inhibitors (HR = 0.84, 95%CI = 0.74–0.95, P < 0.001) were superior to chemotherapy in treatment naïve (upfront) patients, the results were similar in treatment refractory patients (PD-1 inhibitors (HR = 0.67, 95%CI = 0.60–0.75, P < 0.001) and PDL-1 inhibitors (HR = 0.78, 95%CI = 0.69–0.88, P < 0.001) were superior to chemotherapy). There was no difference in the effect of PD-1 and PDL-1 classes of CPIs over chemotherapy in treatment naïve and treatment refractory settings (Q = 1.88, df = 1, P = 0.017, and, Q = 3.27, df = 1, P = 0.070, respectively). Conclusion Efficacy of PD-1 and PDL-1 class of CPIs was not different, although differences among individual CPIs or their combinations cannot be excluded. We were also able to compute pooled efficacy data, as compared to chemotherapy alone, for trials where these groups of CPIs were utilized.
The Role of Defensive Pessimism and Love and Sex Perception on Rape Victim Blame Attribution among Public Servants in a Nigerian City

Existing literature have decried the propensity to blame victims of rape which ultimately translates worryingly into a tolerance of crimes against persons. Being a lopsided and an understudied phenomenon, the present study sets out to explore the role of defensive pessimism and love, and sex perception on rape victim blaming among civil servants in Akwa Ibom State Civil Service Commission, Nigeria. Using a cross-sectional survey research design, 167 civil servants were recruited, comprising 84 males and 83 females, with mean age of 36.29 and standard deviation of 8.53. To measure variables of interest, three instruments: Perception of Love and Sex Scale, Attitudes Towards Rape Victims Scale, and the revised Defensive Pessimism Questionnaire were adopted. To analyze the information obtained from the measuring instruments, descriptive and regression statistics were employed, and results indicated that the less defensive pessimism civil servants reported, the more victim blame they exhibited. Findings also revealed that civil servants who perceived love and sex negatively reported more victim blame. From this study, a new link was formed between variables of interest and the need for adequate mass sensitization on the urgent need of condemning strongly acts of rape and sexual assaults, coupled with advocacy for desensitization on victim blame among “survivors” (rape victims).
Machine learning from wristband sensor data for wearable, noninvasive seizure forecasting

Seizure forecasting may provide patients with timely warnings to adapt their daily activities and help clinicians deliver more objective, personalized treatments. Although recent work has convincingly demonstrated that seizure risk assessment is in principle possible, these early approaches relied largely on complex, often invasive setups including intracranial electrocorticography, implanted devices, and multichannel electroencephalography, and required patient‐specific adaptation or learning to perform optimally, all of which limit translation to broad clinical application. To facilitate broader adaptation of seizure forecasting in clinical practice, noninvasive, easily applicable techniques that reliably assess seizure risk without much prior tuning are crucial. Wristbands that continuously record physiological parameters, including electrodermal activity, body temperature, blood volume pulse, and actigraphy, may afford monitoring of autonomous nervous system function and movement relevant for such a task, hence minimizing potential complications associated with invasive monitoring and avoiding stigma associated with bulky external monitoring devices on the head.
