Abstract
Background Chinese college students used to eat in student canteens, making dietary consumption outside the cafeterias the main reason for the difference in sodium intake. This study aims to develop and validate a food frequency questionnaire (Sodium-FFQ) targeting dietary sodium intake outside the canteens among undergraduates in China. Methods This cross-sectional study included 124 and 81 college students from comprehensive universities in the development and validation stage. A 24 h dietary recall and a food frequency questionnaire were used to develop the Sodium-FFQ. Food items were selected according to the foods that contributed more to the total sodium intake. Test-retest correlation coefficients with an interval of 14 days were employed to evaluate reproducibility. Validity was assessed against a single 24 h urine collection and a 3-day dietary record using correlation coefficients, Bland-Altman analyses, and cross-classification analysis of Kappa coefficients. Results The Sodium-FFQ consists of 12 groups of foods with 48 items. The Spearman correlation coefficient of test-retest on sodium intake was 0.654 (p < 0.05), and that between the Sodium-FFQ, 3 × 24 h dietary record, and 24-h urinary sodium were 0.393 (p < 0.05) and 0.342 (p < 0.05), respectively. The Sodium-FFQ was correlated to 24 h urinary sodium-to-potassium ratio, with a Spearman coefficient of 0.370 (p < 0.05). The classification agreement of the Sodium-FFQ and 24 h urinary sodium was 68.4%, and the Kappa coefficient was 0.371 (p < 0.001). Conclusion The Sodium-FFQ developed in this study presented an acceptable reproducibility, validity, and classification agreement. It indicates that the Sodium-FFQ could be a potential tool for promoting sodium restriction in college students.

Abstract
There are many causes of cauda equina (CE) thickening on neuroimaging of the lumbar spine. The imaging features of CE thickening for the various conditions often overlap and are non-specific to clinch a definite diagnosis. Hence, the imaging findings have to be discerned in accordance with the patient's presenting history, clinical examination findings, and results from electrophysiology and laboratory studies. In this review, the authors aim to supplement the existing literature on imaging findings of CE thickening with a diagnostic framework for clinical workup. The authors also aim to familiarise readers with the interpretation of CE thickening on magnetic resonance imaging (MRI) and would like to illustrate the normal variants and pitfalls that could be mistaken for abnormal results.

Abstract
(1) Background: Insufficient evidence exists regarding the dietary habits that may contribute to high sodium intake among college students in China. This cross-sectional study aimed to investigate the dietary sodium intake of college students in Hunan and its association with their dietary habits. (2) Methods: In total, 585 university students from Hunan were recruited for this study. The sodium Food Frequency Questionnaire (sodium-FFQ) and dietary habits were assessed. (3) Results: Excluding cooking salt and high-sodium seasonings, the daily dietary sodium intake among college students in Changsha, Hunan Province, was 1183.74 (563.38, 2054.86) mg/day. A vast majority (89%) of college students reported eating outside of school at least once a week, and approximately one-third (34%) ordered takeaways at least once a week. After adjusting for confounding factors, the associations between the frequency of eating out and ordering takeaways with college students' sodium intake remained significant. (4) Conclusions: The findings indicate that excessive dietary sodium intake among college students in Hunan is a growing concern. College students who frequently eat out and order takeaways tend to have a higher sodium intake. Future research should focus on identifying the main sources of dietary sodium and developing interventions that promote healthy dietary habits among college students.

Abstract
This study explores the relationship between parental food neophobia, feeding practices, and preschoolers' food neophobia in China. METHODS A cross-sectional study was conducted among 1616 pairs of preschoolers and their parents. Electronic questionnaires were conducted to collect information about social and demographic characteristics, scores of food neophobia among both children and their parents, parents' feeding patterns and children's dietary quality. RESULTS Children's average food neophobia score was 23.72 ± 4.45. There was a positive correlation between parental food neophobia score (β: 0.154; 95%CI: 0.113, 0.195), pressure to eat (β: 0.694; 95%CI: 0.423, 0.964), postpartum breastfeeding initiation (β: 0.010; 95%CI: 0.002, 0.018), and children's score of food neophobia. However, parental modeling (β: -0.470; 95%CI: -0.732, -0.207) and the frequency of children eating with their families at home (β: -0.407; 95%CI: -0.707, -0.108) were negatively associated with children's food neophobia scores. The consumption frequencies of vegetables(P < 0.001), fruits(P < 0.001), domestic animals and poultry(P < 0.01), aquatic products(P < 0.05), beans and their products(P < 0.01), eggs(P < 0.05) and nuts(P < 0.05) and children's dietary diversity score (P < 0.001) are negatively associated with children' food neophobia score. While the consumption frequencies of fast food(P < 0.001), sweets(P < 0.01) and puffed/fried food(P < 0.001) were positively associated with children's food neophobia. CONCLUSION Chinese preschoolers' food neophobia needs more attention because children with high food neophobia tend to have lower dietary quality. Children whose parents have high-level food neophobia should be the focus of early prevention. Earlier postpartum breastfeeding, more use of parental modelling, less pressure to eat and higher frequency of children eating with families are helpful to reduce the incidence of children's food neophobia.

Abstract
Breast milk is a perfect food for infants; however, the rate of exclusive breastfeeding is low. The relationship between exclusive breastfeeding practices and influencing factors is complex and remains unclear. This cross-sectional study was conducted in Changsha County, China, and 414 mothers were enrolled. An online questionnaire was used to collect data on general information, obstetrics and gynecology characteristics, the initial breastfeeding intention, breastfeeding practice, frequency of attending conventional breastfeeding programs before delivery, the status of breastfeeding self-efficacy, and the status of perceived social support. Structural equation modeling (SEM) was used to estimate the association between exclusive breastfeeding and potential risk factors of failing to practice exclusive breastfeeding for 6 months. The rate of exclusive breastfeeding for 6 months was 46.1%. The median and interquartile range of the scores for breastfeeding self-efficacy and perceived social support were 51.0 (18.0) and 68.0 (20.0), respectively. Factors that were statistically significant in the univariate analysis were included in the SEM and model fitness was acceptable based on the results. Exclusive breastfeeding for 6 months was directly associated with intention and self-efficacy, while it was indirectly associated with perceived social support and frequency of attending a breastfeeding program. The findings support the recommendation that comprehensive breastfeeding promotion strategies should be implemented to call on the intention and self-efficacy of breastfeeding mothers through various measures, such as education or providing medical and health services.

Abstract
(1) Background: Research has shown that chronic inflammation can increase the risk of depression. The dietary inflammatory index (DII) is a novel measure of dietary inflammation, which has been used to investigate the relationship between diet and mental disorders in adults. However, little research has been conducted to establish an association between dietary inflammation (as measured by DII) and postpartum depression (PPD) in exclusively breastfeeding women. (2) Methods: In this cross-sectional study, 293 women who were exclusively breastfeeding for 6 months or less were enrolled. The DII scores were evaluated using semi-quantitative Food Frequency Questionnaires (FFQ), and the Edinburgh Postpartum Depression Scale (EPDS) was used to measure depression levels of breastfeeding mothers during the six months following delivery. The participants were classified by tertiles, and the possibility of DII being associated with PPD was assessed by binary regression analysis. (3) Results: The average DII score was 2.32 ± 1.08, which ranged from -1.66 to 4.19. The rate of depression was 60.1%. Adjusted for potential risk factors such as age, educational level, occupational level, number of babies, number of caregivers, social support level, and sleep quality, the results showed that the lowest DII score was associated with a lower risk of PPD than the highest score (OR tertile Q1 vs. 3 = 0.47, 95% CI: 0.24, 0.93, p = 0.030). (4) Conclusions: In exclusive breastfeeding women, the inflammatory potential of dietary intake seems to be related to depression. Interventions to improve diet quality might consider including a dietary component that aims to lower chronic systemic inflammation to prevent PPD. However, the relationship between DII and PPD among Chinese women remains to be demonstrated in a larger population.

Abstract
BackgroundGlucocorticoid therapy is the mainstay treatment for GCA. There is no consensus on the dose of prednisolone to be used. Prednisolone regimens used in clinical trials have reported relapse rates of 66 to 92%. The long-term follow-up of Tocilizumab and prednisolone for 1-year showed a relapse rate of 74% at 2 years. The Norwich Regimen is a bespoke prednisolone plan with an initial dose of 1mg/kg of lean body mass. It delivers 164.64 mg/kg of lean body mass in a logarithmic taper over 100 weeks. It was devised to reduce the risk of relapse and allow patients to be in control of their prednisolone reduction.ObjectivesTo document drug-free survival at 150 weeks of people with GCA treated with a bespoke prednisolone taperMethodsAll patients were diagnosed by biopsy, ultrasonography or PET scan and provided with a printed prednisolone plan at diagnosis. All individuals were assessed at approximately 3-6 monthly intervals in addition to suspected relapse, toxicity or other need for course correction. Relapses were confirmed objectively using a modification of the Kerr criteria. Relapse free survival was recorded at 100 weeks. Patients were given an open invite to contact us in the event of a suspected relapse after coming off prednisolone. A notes review was done to record events at 150 weeks.Results150 consecutive people with objectively diagnosed GCA (mean age 74) since 10/01/2012 have completed 150 weeks since starting prednisolone. Drug-free, relapse-free survival at 100 weeks was met by 133/150 (89%). 7 individuals died and 20 relapsed. A further 5 died and 15 relapsed by week 150; 103/150 (69%) survivors were in prednisolone-free remission. Of the 12 deaths – 6 died of cancer, 1 subdural haemorrhage, 1 ischaemic bowel, 1 septicaemia, 1 general decline (aged 93). The cause of death was not available for 2 individuals who died in the community. The median time to relapse for the 35 individuals was 80 weeks (IQR 64,109).ConclusionWe report the first results of a bespoke prednisolone taper to be used in real life. The Norwich Regimen for the treatment of GCA results in drug-free relapse-free survival of 89% at 100 weeks and 69% at 150 weeks, which is superior to all other reports published so far.References[1]Mukhtyar, C, Cate, H, Graham, C, Merry, P, Mills, K, and Misra, A, 2019, ‘Development of an evidence-based regimen of prednisolone to treat giant cell arteritis – the Norwich regimen’ Rheumatology Advances in Practice, Volume 3, Issue 1, 2019, rkz001, https://doi.org/10.1093/rap/rkz001[2]Hellmich B, Agueda A, Monti S, et al2018 Update of the EULAR recommendations for the management of large vessel vasculitis Annals of the Rheumatic Diseases 2020;79:19-30.Disclosure of InterestsNone declared

Abstract
This study aimed to examine the prevalence, associated factors and perceptions of dietary supplement use among pregnant Chinese women. A cross-sectional study was conducted to collect data about prevalence, purchase channels, perceptions, and related factors of dietary supplement use from 572 pregnant women, through a face-to-face survey, using a self-designed questionnaire. Of the respondents, 94.8% used at least one dietary supplement, whereas 29.8% used more than four supplements in the previous month. The majority of the pregnant women were highly educated (81.2% had a bachelor’s degree or above) and had the perception that dietary supplements could prevent and improve (89.2%), or treat, nutrition-related diseases (78.7%). Multivariate analysis showed that pregnant women who had used multiple (more than four) supplements were more likely to have a larger gestational age, received fertility treatment, more prenatal visits, and hypothyroidism during pregnancy. Furthermore, pregnant women not only purchased dietary supplements through hospitals (72.6%) and pharmacies (45.1%), but overseas Daigou or online purchases (31.8%) were also a major channel of purchase. A high prevalence of dietary supplement use during pregnancy was observed, with extensive and repeated consumption of nutrients. Pregnant women’s craze for dietary supplements calls for more comprehensive guidelines in China.

Abstract
This study aimed to investigate the prevalence of excessive daytime sleepiness (EDS) and explore the association between free sugars intake and EDS. In this cross-sectional study, a total of 1517 middle school students (808 boys and 707 girls) aged 12~14 years were recruited. The study was conducted in Changsha city, China. Adolescents completed an online questionnaire, including the Epworth Sleepiness Scale (ESS), sleep characteristics, a 12-item Food Frequency Questionnaire (FFQ), and other self-reported information. The ESS score ≥ ten was defined as EDS. The anthropometric indices, including height, weight, and waist circumference, were measured and recorded by uniformly trained assistants. Statistical analyses included the Chi-square test and binary logistic regression model. The mean ESS score and free sugars consumption were 6.8 ± 3.9 points and 53.1 ± 44.7 g/d, respectively. The prevalence of EDS among adolescents was 22.5%, and more girls than boys had EDS (26.1% vs. 19.4%, p < 0.05). An exceeded free sugars intake was positively associated with EDS, with the adjusted Odds Ratio (OR) with its 95% Confident Interval (95% CI) of 1.366 (1.060~1.761, p < 0.05). EDS and excessive consumption of free sugars are commonly found among Chinese adolescents. Further studies are needed to confirm whether free sugars restriction can be meaningful to improve daytime drowsiness in those with EDS.

Abstract
Parental perception of children’s weight may influence parents’ feeding practices, and in turn, child dietary intake and weight status; however, there is limited evidence generated for preschoolers. The aim of this cross-sectional study was to investigate associations between Chinese parents’ perceptions of child weight, feeding practices and preschoolers’ dietary patterns. Participants (1616 parent-child pairs) were recruited from six kindergartens in Hunan, China. Parents’ misperception, concern, and dissatisfaction on child weight were collected through a self-administered caregiver questionnaire. Parental feeding practices and children’s dietary intake were, respectively, assessed using the Child Feeding Questionnaire and a Food Frequency Questionnaire. Linear regression models were applied to analyze associations between parental weight perceptions, feeding practices, and preschooler’s dietary patterns. Associations between parents’ weight perceptions and dietary patterns were significant only among underweight children. Regardless of child weight status, parental weight underestimation and preference for a heavier child were positively associated with pressure-to-eat. Parental weight concern was positively associated with restriction in normal weight child, but this was not found in other weight groups. In conclusion, Parents’ misperception, concern, and dissatisfaction about child weight are associated with parents’ feeding practices and may influence preschoolers’ dietary quality, but the relationships vary by children’s actual weight status.

Abstract
Abstract
Background
The natural history of native valvular moderate aortic stenosis (AS) is poorly understood.
Purpose
To examine the prognosis of patients with native valvular moderate AS, and identify high risk-features associated with increased mortality.
Methods
Natural language processing of electronic health records in the claims-linked Optum® database (2011–2018) from over 200 hospitals and 7000 clinics in the United States identified severity of AS (mild/moderate/severe) from echocardiograms and physician notes of patients more than 65 years old. Our cohort included 30,204 patients (3594 with mild, 9938 with moderate, and 16672 with severe AS). We used competing risk Kaplan-Meier analysis to compare 5-year mortality (obtained from the Social Security Death Masterfile) between the different AS severity groups adjusted for demographics and comorbidities, censoring for aortic valve replacement. The relationship between AS severity and survival was examined during median 1049 days (interquartile range: 597 to 1652 days) of follow-up. We performed Fine-Gray modeling to examine risk factors associated with long-term mortality in patients with moderate AS.
Results
A higher proportion of comorbidities like atrial fibrillation, diabetes, and coronary artery disease were observed with increasing severity of AS (Figure 1). After adjustment, compared with mild AS (5-year mortality: 31.6%), patients with untreated moderate (5-year mortality: 40.0%, HR 1.34, 95% CI 1.25 – 1.44) and untreated severe AS (5-year mortality: 51.1%, HR 1.88, 95% CI 1.75– 2.01) have increasing risk of long-term mortality (Figure 2). Significant predictors of 5-year mortality in patients with moderate AS include older age (HR 1.38, 95% CI 1.29 –1.47), male sex (HR 1.21, 95% CI 1.15 – 1.27), heart failure (HR 1.37, 95% CI 1.29 – 1.44), coronary artery disease (HR 1.20, 95% CI 1.13 – 1.27), and atrial fibrillation (HR 1.08, 95% CI 1.02 – 1.14). In a subcohort of 5189 patients for whom left ventricular ejection fraction (LVEF) information was available, reduced LVEF was associated with worse long-term mortality (LVEF<40%: HR 1.17, 95% CI 1.05 –1.31; LVEF 40–50%: HR 1.08, 95% CI 0.97 –1.20).
Conclusion
Our findings suggest that moderate AS is associated with poor long-term survival with higher risk associated with LVEF <40%, and comorbidities including heart failure, coronary artery disease and atrial fibrillation. Whether patients with moderate AS, particularly with high-risk features, benefit from treatment remains unknown.

Abstract
This study aims to explore the association between restrained eating, body image, and dietary intake among Chinese college students. This cross-sectional study included 1301 college students at two universities in Hunan Province. Electronic questionnaires were used to collect information including students’ demographic characteristics, restrained eating, perception of body weight, body satisfaction, and dietary intake. Anthropometric measurements were collected to calculate body mass index (BMI). The prevalence of high restrained eating was 52.8%. Students who were dissatisfied with their bodies or overestimated their body weight showed a higher tendency toward high restrained eating (p < 0.05). Students with high restrained eating tended to eat fruits and eggs more frequently, while the frequency of eating domestic animals and poultry, sugar-sweetened beverages, and fast food were the opposite. Moreover, high restrained eating was a risk factor for low dietary diversity (odds ratio (OR) = 1.384, 95% confidence interval: 1.002~1.912). The high incidence of restrained eating among Chinese college students and its energy-restricted diets that may lead to possible health implications require attention. Further studies are needed to investigate the characteristics of college students’ restrained eating to tailor appropriate interventions for forming positive body images and promoting healthy eating behaviors, thus, improving dietary quality.

Abstract
This study aims to explore associations between emotional eating, depression and laryngopharyngeal reflux among college students in Hunan Province. METHODS This cross-sectional study was conducted among 1301 students at two universities in Hunan. Electronic questionnaires were used to collect information about the students' emotional eating, depressive symptoms, laryngopharyngeal reflux and sociodemographic characteristics. Anthropometric measurements were collected to obtain body mass index (BMI). RESULTS High emotional eating was reported by 52.7% of students. The prevalence of depressive symptoms was 18.6% and that of laryngopharyngeal reflux symptoms 8.1%. Both emotional eating and depressive symptoms were associated with laryngopharyngeal reflux symptoms (AOR = 3.822, 95% CI 2.126-6.871 vs. AOR = 4.093, 95% CI 2.516-6.661). CONCLUSION The prevalence of emotional eating and depressive symptoms among Chinese college students should be pay more attention in the future. Emotional eating and depressive symptoms were positively associated with laryngopharyngeal symptoms. The characteristics of emotional eating require further study so that effective interventions to promote laryngopharyngeal health among college students may be formulated.

Abstract
Abstract
Background
Renal transplant surgeons are making increasing use of live donor kidneys with multiple renal arteries. This study aimed to identify independent risk factors for the development of transplant renal artery stenosis (TRAS) in the modern era of complex arterial reconstruction for multiple vessels.
Methods
Multivariable logistic regression analysis with a stepwise variable deletion model was used to identify risk factors for the development of TRAS in a consecutive series of live donor kidney transplants.
Results
Of 506 kidney transplants, 19 (3·8 per cent) had evidence of significant TRAS on CT angiography. Functional TRAS, defined by improvement in BP control or renal function after correction of a stenosis by angioplasty, occurred in 13 of 506 patients (2·6 per cent). Independent risk factors for TRAS were: use of an explanted internal iliac artery graft from the recipient (odds ratio (OR) 4·95; P = 0·020) and total ischaemia time (OR 1·82; P = 0·010). TRAS was associated with a lower 5-year allograft survival rate (79 versus 88·7 per cent; P = 0·020) but only one graft loss was attributed directly to TRAS. The 5-year allograft survival rate after internal iliac artery grafting was 86 per cent.
Conclusion
Although use of an internal iliac artery graft is an independent risk factor for TRAS after live donor kidney transplantation, this technique is still a useful option for complex arterial reconstruction.

Abstract
Objective To establish the primary cat intestinal epithelial cells (IECs) culture methods and construct the cDNA library for the following yeast two-hybrid experiment, so as to screen the virulence interaction factors among the final host. Methods The primary cat IECs were cultured by the tissue cultivation and combined digestion with collagenase XI and dispase I separately. Then the cat IECs cultured was identified with the morphological observation and cyto-keratin detection, by using goat anti-cyto-keratin monoclonal antibodies. The mRNA of cat IECs was isolated and used as the template to synthesize the first strand cDNA by SMART™ technology, and then the double-strand cDNAs were acquired by LD-PCR, which were subsequently cloned into the plasmid PGADT7-Rec to construct yeast two-hybrid cDNA library in the yeast strain Y187 by homologous recombination. Matchmaker™ Insert Check PCR was used to detect the size distribution of cDNA fragments after the capacity calculation of the cDNA library. Results The comparison of the two cultivation methods indicated that the combined digestion of collagenase XI and dispase I was more effective than the tissue cultivation. The cat IECs system of continuous culture was established and the cat IECs with high purity were harvested for constructing the yeast two-hybrid cDNA library. The library contained 1.1×106 independent clones. The titer was 2.8×109 cfu/ml. The size of inserted fragments was among 0.5-2.0 kb. Conclusion The yeast two-hybrid cDNA library of cat IECs meets the requirements of further screen research, and this study lays the foundation of screening the Toxoplasma gondii virulence interaction factors among the cDNA libraries of its final hosts.

Abstract
OBJECTIVE To evaluate the performance of contrastenhanced ultrasound (CEUS) in the risk stratification of indeterminate renal lesions picked up incidentally on abdominal imaging, in patients with renal impairment. METHODS A retrospective study was performed of nonconsecutive patients who underwent CEUS at our tertiary care centre for indeterminate renal lesions between March 2010 and September 2014. A total of 63 patients with 74 nodules were assessed with CEUS and stratified into either benign (Bosniak I, II, IIF) or suspicious for malignancy (Bosniak III, IV or hypervascular solid lesions). Diagnostic accuracy was determined by comparing these findings to subsequent histological diagnoses, temporal change after at least 20 months follow-up or after a diagnostic computer tomography / magnetic resonance imaging study. RESULTS CEUS correctly identified 49/52 (94.2%) of benign lesions and 21/22 (95.5%) of malignant lesions, resulting in a sensitivity of 95.5% (95% CI 77.2-99.9%), specificity of 94.2% (95% CI 84.1-98.8%), positive predictive value (PPV) 87.5% (95% CI 67.6-97.3) and negative predictive value (NPV) 98.0% (95% CI 89.4-100%). CONCLUSION CEUS has high diagnostic performance in predicting the benignity of a renal lesion in patients with renal impairment, showing sensitivity and NPV approaching 100%.

Abstract
A 22-year-old man with primitive trigeminal artery-cavernous fistula was admitted to our hospital. Embolization with Guglielmi detachable coils and microcoils was attempted on the fistula from the internal carotid artery. The last microcoil was incorrectly released to the basilar artery through the primitive trigeminal artery. The misplaced microcoil was eventually retrieved by goose-neck snare. There was no related complication in the follow-up period.

Abstract
For liver-targeted regenerative medicine, embryonic stem (ES) cell-derived hepatocyte-like cells proffer great expectation. In vitro exposure to a combination of various growth factors, such as hepatocyte growth factor and fibroblast growth factor-4, as well as cytokines, leads to differentiation of ES cells into hepatocyte-like cells. We sought to determine the in vivo environment that allowed engraftment of ES cells transplanted to the liver. Thus, we examined the effect of partial hepatectomy (50%) (PHT) and subsequent radiation (RT) of the male Balb/c mouse host liver on ES cell engraftment. ES cells (5 x 10(6)) derived from 129Sv mice were transplanted into the residual liver. The controls were ES cells transplanted into a normal liver. Bromo-deoxy-residine (BrdU)-uptake was performed to evaluate the effect of hepatectomy and RT on hepatocyte regeneration. Mouse ES cells engrafted, forming teratomas in the normal liver without showing any mononuclear infiltration. A liver modified by PHT and RT facilitated engraftment of mouse ES cells compared with a normal liver. Hepatic RT significantly suppressed hepatocytic uptake of BrdU.

Abstract
Parallel dynamics of neural networks with separable coupling is given starting from Coolen-Sherrington theory. Away from saturation, it is shown that this parallel retrieve dynamics is equivalent to the sequential dynamics for finite temperature. But the finite-size effects were found to be governed by a homogeneous Markov process, not by a time-dependent Ornstein-Uhlenbeck process in sequential dynamics.

Abstract
We report on the role of vpu in the pathogenesis of a molecularly cloned simian-human immunodeficiency virus (SHIV(KU-1bMC33)), in which the tat, rev, vpu, env, and nef genes derived from the uncloned SHIV(KU-1b) virus were inserted into the genetic background of parental nonpathogenic SHIV-4. A mutant was constructed (DeltavpuSHIV(KU-1bMC33)) in which 42 of 82 amino acids of Vpu were deleted. Phase partitioning studies revealed that the truncated Vpu was not an integral membrane protein, and pulse-chase culture studies revealed that cells inoculated with DeltavpuSHIV(KU-1bMC33) released viral p27 into the culture medium with slightly reduced kinetics compared with cultures inoculated with SHIV(KU-1bMC33). Inoculation of DeltavpuSHIV(KU-1bMC33) into two pig-tailed macaques resulted in a severe decline of CD4(+) T cells and neurological disease in one macaque and a more moderate decline of CD4(+) T cells in the other macaque. These results indicate that a membrane-bound Vpu is not required for the CD4(+) T cell loss and neurological disease in SHIV-inoculated pig-tailed macaques. Furthermore, because the amino acid substitutions in the Tat and Rev were identical to those previously reported for the nonpathogenic SHIV(PPc), our results indicate that amino acid substitutions in the Env and/or Nef were responsible for the observed CD4(+) T cell loss and neurological disease after inoculation with this molecular clone.

Abstract
The terfenadine-pseudoephedrine dosage form discussed here is the sustained-release core tablet composed of outer (fast-release) and inner (sustained-release) layers. To develop the double-layer tablet dissolution-equivalent to a core tablet, the fast-release and sustained-release layers were prepared using various disintegrants and polymers, respectively. The layer composed of terfenadine/pseudoephedrine/lactose/cornstarch/sodium bicarbonate/hydroxypropylcellulose (HPC)/sodium lauryl sulfate/microcrystalline cellulose (60/10/90/30/20/1/40/1/293 mg), which gave the fast disintegration time and high dissolved amounts of drugs, was selected as the fast-release layer. The dissolved amounts of pseudoephedrine from sustained-release layers increased more with a smaller ratio of ethylcellulose and hydroxypropylmethylcellulose (HPMC). Dissolution mechanism analysis showed the release of pseudoephedrine was proportional to the square root of time, indicating that drug might be released from the layers by Fickian diffusion. The layer composed of pseudoephedrine/ethylcellulose/HPMC (110/30/155 mg), which had similar dissolution amounts of pseudoephedrine as the inner layer of a core tablet, was selected as the sustained-release layer. Furthermore, the dissolved amounts of drugs from the core and double-layer tablets had deviations of less than 5% against the average dissolved amounts of drugs at each time. There was no significant difference between the dissolved amounts of drugs from these tablets at each time in pH 1.2, 4.0, and 6.8 (P > .05). Our results suggest that this double-layer tablet was a dissolution equivalent to the core tablet.

Abstract
The yeast Saccharomyces cerevisiae transcription factor Ste12p is responsible for activating genes in response to MAP kinase cascades controlling mating and filamentous growth. Ste12p is negatively regulated by two inhibitor proteins, Dig1p (also called Rst1p) and Dig2p (also called Rst2p). The expression of a C-terminal Ste12p fragment (residues 216 to 688) [Ste12p(216-688)] from a GAL promoter causes FUS1 induction in a strain expressing wild-type STE12, suggesting that this region can cause the activation of endogenous Ste12p. Residues 262 to 594 are sufficient to cause STE12-dependent FUS1 induction when overexpressed, and this region of Ste12p was found to bind Dig1p but not Dig2p in yeast extracts. In contrast, recombinant glutathione S-transferase-Dig2p binds to the Ste12p DNA-binding domain (DBD). Expression of DIG2, but not DIG1, from a GAL promoter inhibits transcriptional activation by an Ste12p DBD-VP16 fusion. Furthermore, disruption of dig1, but not dig2, causes elevated transcriptional activation by a LexA-Ste12p(216-688) fusion. Ste12p has multiple regions within the C terminus (flanking residue 474) that can promote multimerization in vitro, and we demonstrate that these interactions can contribute to the activation of endogenous Ste12p by overproduced C-terminal fragments. These results demonstrate that Dig1p and Dig2p do not function by redundant mechanisms but rather inhibit pheromone-responsive transcription through interactions with separate regions of Ste12p.

Abstract
An outbreak of an influenza like illness was found in a nursing home in Fukuoka in January, 1999. Results of hemagglutinin inhibition tests with paired sera of patients and rapid diagnosis kit for influenza A indicated that an influenza A (H3N2) outbreak had occurred. A total of 15 patients with influenza like illness from one residential area of the nursing home were administered amantadine, 100 mg per day for five days. Clinical records of 264 residents were surveyed retrospectively from the tenth to the thirty-first of January, 1999. Influenza like illness was found in 112 residents (42.4%). The incidence of influenza like illness differed by residential area, ranging from 27.6% to 54.0%. The mean duration of fever was 3.6 days among patients administered amantadine. The mean duration was 4.4 days for patients not administered amantadine. The incidence of influenza like illness decreased rapidly after amantadine administration in the residential area where amantadine administration was done. These results suggest that amantadine is effective in mitigating influenza symptoms in the elderly. Amantadine may be useful for diminishing the influence of influenza A outbreaks in nursing homes.

Abstract
To investigate the efficacy of influenza vaccine in the elderly, hemagglutination inhibition (HI) antibody titer for the three types of influenza viruses were measured and the influenza infection rate was determined serologically in geriatric inpatients. Influenza vaccination was done for inpatients. For patients who had influenza vaccination in the year prior to the study, influenza vaccine was administered once or twice, and the number of injections were determined randomly. Influenza vaccine was injected twice to those had not received influenza vaccine in the previous year. Serum samples were collected from 166 vaccinated and 104 unvaccinated patients before and after 1996/1997 influenza season. In the vaccinees who had been vaccinated the previous year, 56 patients were injected once and 58 patient were injected twice. Fifty-two patients had not been vaccinated the previous year. Serologically diagnosed influenza infection rate in the 104 unvaccinated patients was 16.3% for influenza A/H3N2 and 8.7% for influenza B. The infection rate was 3.0% for influenza A/H3N2 and 0.6% for influenza B in the 166 vaccinated patients. The infection rates were significantly lower in the vaccinees than in the unvaccinated patients (p < 0.001 with A/H3N2 and p < 0.01 with B). There was no significant difference in the infection rate among the three vaccinated groups. These results suggest that the influenza vaccination had significant protective efficacy for influenza infection in the elderly. Prior vaccination did not diminish the efficacy of the influenza vaccine. The efficacy of a single influenza vaccine injection was equivalent to that of two injection.

Abstract
HIV-1 causes cognitive and motor deficits and HIV encephalitis (HIVE) in a significant proportion of AIDS patients. Neurological impairment and HIVE are thought to result from release of cytokines and other harmful substances from infected, activated microglia. In this study, the quantitative relationship between microglial activation and neurological impairment was examined in the simian immunodeficiency model of HIVE. Macaque monkeys were infected with a passaged, neurovirulent strain of simian immunodeficiency virus, SIV(mac)239(R71/17E). In concurrent studies, functional impairment was assessed by motor and auditory brainstem evoked potentials and by measurements of cognitive and motor behavioral deficits. Brain tissue was examined by immunohistochemistry using two markers of microglia activation, MHC-II and matrix metalloproteinase-9 (MMP-9). The inoculated animals formed two groups: rapid progressors, which survived 6-14 weeks postinoculation, and slow progressors, which survived 87-109 weeks. In the rapid progressors, two patterns of MHC-II expression were present: (1) a widely disseminated pattern of MHC-II expressing microglia and microglial nodules in cortical gray matter and subcortical white matter, and (2) a more focal pattern in which MHC-II expressing microglia were concentrated into white matter. Animals exhibiting both patterns of microglial activation showed mild to severe changes in cognitive and motor behavior and evoked potentials. All rapid progressors showed expression of MMP-9 in microglia located in subcortical white matter. In the slow progressors MHC-II and MMP-9 staining was similar to uninoculated control macaques, and there was little or no evidence of HIVE. These animals showed behavioral deficits at the end of the disease course, but little changes in evoked potentials. Thus, increases in MHC-II and MMP-9 expression are associated with development of cognitive and motor deficits, alterations in evoked potentials, and rapid disease progression.

Abstract
In this study, the human general transcription factor IIF (TFIIF), a heteromeric complex of RAP74 and RAP30 subunits, was subjected to limited proteolysis with trypsin. The central region of RAP74 was demonstrated to be highly sensitive to trypsin while both the N- and C-terminal regions contained trypsin-resistant structures. In contrast, RAP30 digestion occurred after proteolysis of RAP74. The digestion pattern of RAP74 recruited into the preinitiation complex showed no marked difference from that of IIF, while RAP30 in the complex was protected from trypsin. These results indicate that RAP74 apparently contains three structural domains, the central one of which is externally surfaced and unstructured, but RAP30 is internally wrapped by RAP74. Furthermore, the accessibility of the central region of RAP74 is unaltered in the minimal preinitiation complex, while RAP30 is involved in promoter recognition through its DNA binding activity.

Abstract
Following a controlled, severe contusion lesion to the lower thoracic spinal cord in adult rats, we found that apoptosis occurred in cells located in both gray and white matter. This suggested that both nonneuronal cells, including astrocytes, oligodendroglia and microglia, as well as neurons, might participate in programmed cell death (PCD) following spinal cord injury (SCI). Determination of which cell populations participate, and the kinetics and extent of their involvement might reveal new paradigms for approaches to therapy. Consequently, we assessed the functional deficit, comparing a comprehensive locomotor rating scale (LRS) with the inclined plane test at various times after injury. Using standard histology, along with cell-specific markers, we assessed PCD in different spinal cord segments using several parameters of apoptosis. Our results indicate that hind limb motor function was lost at day 1, and then only gradually and ineffectively (about 10-15%) recovered over the next month. Evidence for increased cell number was present for astrocytes and microglia beginning at day 1 after injury. Over the postinjury time period, apoptotic cells appeared (from day 1 to 14), and peaked (in terms of apoptotic index) on day 3. About one-third were microglia, whereas neurons, both large and small, also underwent apoptosis, again peaking at day 3. However, neurons continued to die and were not replaced by proliferation, so that at day 7, three times as many neurons (as a percentage) underwent PCD compared with the glial compartment. Oligodendrocytes also underwent apoptosis, with a biphasic curve, both at days 3 and 14 following injury. Thus, in addition to immediate, passive necrosis, delayed and apoptotic PCD also occurred in all cell populations in severely injured spinal cord.

Abstract
Astrocyte activation has been postulated to be a major contributor to functional changes in the brain of AIDS patients. We assessed astrocyte activation in the simian immunodeficiency virus (SIV) model. Four groups of macaque brains were examined: uninoculated controls, animals inoculated with virus that did not cause disease, animals inoculated with virus that caused AIDS but did not cause encephalitis, and animals with SIV encephalitis. We examined expression of calbindin-D-28K, a calcium binding protein that is upregulated in astrocytes during excitotoxic events, as well as glial fibrillary acidic protein (GFAP). The presence of calbindin in astrocytes was confirmed by double-labeling using confocal microscopy. Increases in calbindin staining were most apparent in the white matter, but increases in GFAP staining were most apparent in middle layers of the cerebral cortex. Six of the seven animals with SIV encephalitis had calbindin immunoreactive astrocytes in the subcortical white matter, corpus callosum, internal capsule, cerebral peduncle, pontine white matter, and cerebellar white matter. Very rarely, a few, very lightly calbindin-immunoreactive astrocytes were present in the uninoculated control brains. The increase in calbindin expression by astrocytes in SIV encephalitis suggests that these cells are subject to calcium toxicity. In uninoculated control macaques, and in macaques inoculated with virus that did not cause disease, GFAP-immunoreactive astrocytes were present throughout the subcortical white matter and in layer I, but very few were found in layers III-V of the cerebral cortex. Two animals that died of AIDS without encephalitis had somewhat higher numbers of GFAP immunoreactive astrocytes in middle cortical layers. In seven animals that received passaged neurovirulent virus and developed both AIDS and encephalitis, the number of GFAP-immunoreactive astrocytes in middle cortical layers was high, indicating widespread astrocyte activation.

Abstract
Combination vaccines containing viral and bacterial antigens are commonly used in veterinary practice and have been associated with adverse reactions. A group of young Simmental calves developed fever and depression following administration of a mixed vaccine, and 1 died with pulmonary edema, suggesting that endotoxins or other bacterial components may interact synergistically with some adjuvants to cause an enhanced pathologic inflammatory response in some individuals.
