As the supplement of the flora of Zhejiang, East China, two new species were described with illustrations. Cerastiumhuadingense Y.F.Lu, W.Y.Xie & X.F.Jin (Caryophyllaceae) differs from C.qingliangfengicum in having sterile stems absent, leaves sessile, petals slightly longer than sepals, and stamens slightly shorter than sepals. selleck products Ixeridiumdimorphifolium Y.L.Xu, Y.F.Lu & X.Cai (Asteraceae) differs from I.beauverdianum in having plant stoloniferous, basal leaves dimorphic, involucre 8‒10 mm long, inner phyllaries 8, and florets 7‒10. Paraphlomissetulosa C.Y.Wu & H.W.Li (Lamiaceae) was reviewed and morphological characters of the corolla and stamens of its type and the specimens collected in the field survey were critically examined. With barbate anthers and strongly divergent anther cells, Paraphlomissetulosa was transferred to Sinopogonanthera, and S.setulosa (C.Y.Wu & H.W.Li) H.W.Zhang & X.F.Jin was consequently combined.A new species of Rubiaceae, Spiradiclisdetianensis is described from a limestone karst area of southwestern China. This new species is morphologically similar to S.cordata and S.spathulata. All of them have rosetted habit and long peduncles, but it differs from the former by the cuneate leaf bases (vs. basally cordate) and much longer corolla tubes (1.8-2.2 cm long vs. ca. 5 mm long), and from the latter mainly by its tubular-funnel shaped corolla (vs. slenderly salver shaped), 4.5-6.8 (vs. 1.5-2) mm in diam, inside throat and corolla densely puberulent (vs. glabrous except a ring of long hairs at the middle). It also resembles to S.tubiflora, but differs clearly by its subrosulate habit (vs. procumbent to creeping), longer leaf blades (7.0-10.5 cm vs. 0.5-2.5 cm) and longer corolla tubes (18-22 mm vs. 14-16 mm). At same time, color photos, illustrations, detailed descriptions and conservation status of the new species are provided.Salixlapponum is a cold-tolerant relict species in Europe that occurs in several sites, probably reflecting previous migration routes of S.lapponum during the Pleistocene. However, only a few data are available on the genetic structures of populations of S.lapponum. In this study, we use PCR-ISSR markers to investigate genetic variation in 19 European populations of S.lapponum L. AMOVA analysis shows that most of the variation (55.8%) occurs within populations; variability among groups accounts for 19.7%. An AMOVA analysis based on four groups determined by STRUCTURE analysis shows similar results variability of 54.1% within the population and variability of 18.9% between the four population groups, based on geographic regions. Within individual geographic groups, which are characterised by the studied populations, the lowest variability (as well as the highest homogeneity) was found in populations located in Belarus. The obtained results are consistent with our expectations that the European Lowland could be a significant geographic barrier for gene flow over large geographic distances for S.lapponum. Both the Scandinavian and Belarusian populations, as well as those coming from NE Poland, are characterised by significant genetic distinctiveness. However, some populations from NE Poland and the Sudetes show similarities with populations from other geographic regions, indicating existing genetic relationships between them. Moreover, the results suggest a fairly clear division of the population into 4 emerging geographic regions, although separated by a geographical barrier the Polish lowland, which forms part of the larger geographic unit known as the European Lowland.A cooperative control strategy is proposed for the air conditioning (AC) system and ventilation system to reduce the risk of COVID-19 infection and save the energy of the AC system. This strategy integrates the dynamic model of the AC-cabin system, infection risk assessment, model predictive control (MPC) of the thermal environment inside the cabin, and ventilation control that considers passengers' sneezing. Unlike other existing AC system models, the thermal-health model established can describe not only the system performance but also the virus concentration and risk of COVID-19 infection using the Wells-Riley assessment model. Experiments are conducted to verify the prediction accuracy of the AC-cabin model. The results prove that the proposed model can accurately predict the evolution of cabin temperature under different cases. The cooperative control strategy of the AC system integrates the MPC-based refrigeration algorithm for the cabin temperature and intermittent ventilation strategy to reduce the risk of COVID-19 infection. This strategy well balances the control accuracy, energy consumption of the AC system, and the risk of COVID-19 infection, and greatly reduces the infection risk at the expense of a little rise in the energy consumption.One emerging technology with the potential to improve and further transform the field of orthopaedic surgery is virtual reality (VR). VR has been explored and used in many different specialties with clinical applications, such as psychiatric therapy, pain management, rehabilitation, and traumatic brain injury. Recent studies have suggested that the use of VR during the training of orthopaedic surgery residents produces similar or improved surgical performance by residents. This is an area where VR can provide a tremendous benefit to the field of orthopaedic surgery, as it offers a safe and accessible complement to orthopaedic surgical training outside of the operating room (OR) and without involving patients directly. This review will elucidate the current state of virtual reality use in the training of orthopaedic surgeons and highlight key benefits and challenges in its application as a training resource.Stem cell transplantation has been investigated as treatment for severe and progressive systemic sclerosis (SSc) for the past 25 years. To date, more than 1000 SSc patients have been transplanted worldwide. link2 Overall and event-free survival have increased over the years, reflecting stricter patient selection criteria and better clinical management strategies. This review addresses long-term outcomes of transplanted SSc patients, considering phase I/II and randomized clinical trials, as well as observational studies and those assessing specific aspects of the disease. Clinical outcomes are discussed comparatively between studies, highlighting advances, drawbacks and controversies in the field. Areas for future development are also discussed.Thrombotic thrombocytopenic purpura (TTP) is an uncommon life-threatening condition characterized by hemolytic disorders. The coexistence of systemic lupus erythematosus (SLE) with TTP is extremely rare, although Africans are at increased risk due to inherited risk factors. This report describes a rare clinical manifestation of TTP associated with SLE in a Sudanese patient. A 41-year-old Sudanese woman presented to the emergency department with symptoms and features that were suggestive of malaria, for which she had been treated accordingly. However, a few days later she complained of fever, and was found to have a body temperature of 39.5°C, jaundice, anemia, and thrombocytopenia. Soon after admission, she developed confusion and unrecordable blood pressure. After the patient had stabilized, clinical assessment, immune-system investigation (antinuclear antibody profile, complements, blood panel), and imaging revealed a diagnosis of TTP associated with SLE. The patient received imipenem 500 mg, five sessions of plasmapheresis (60 mL/kg), methylprednisolone 1 g pulse for 3 days, and rituximab 375 mg/week. Three weeks later, the patient was discharged after her condition had improved, and she is now on regular follow-up.

An early prescreening in suspected obstructive sleep apnea (OSA) patients is desirable to expedite diagnosis and treatment. However, the accuracy and applicability of current prescreening tools is insufficient. We developed and tested an unbiased scoring system based solely on objective variables, which focuses on the diagnosis of severe OSA and exclusion of OSA.

The OSA prediction score was developed (n = 150) and validated (n = 50) within German sleep center patients that were recruited as part of the Sleep Apnea Global Interdisciplinary Consortium (SAGIC). Six objective variables that were easy to assess and highly correlated with the apnea-hypopnea index were chosen for the score, including some known OSA risk factors body-mass index, neck circumference, waist circumference, tongue position, male gender, and age (for women only). To test the predictive ability of the score and identify score thresholds, the receiver-operating characteristics (ROC) and curve were calculated.

A score ≥8 for predicting objective measures with predictive power and high general applicability. The proposed tool successfully predicted severe OSA (important due to its high risk of cardiovascular disease) and the exclusion of OSA (rarely a feature of previous screening instruments, but important for better differential diagnosis and treatment).

Patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) have impaired dynamic cerebral autoregulation (dCA). This study aimed to explore whether serum levels of apolipoprotein B-100 (ApoB-100), fibronectin (FN), and ceruloplasmin (CP) were related to impaired dCA in OSAHS.

A total of 90 patients with OSAHS from our database management system were enrolled and further divided into three subgroups according to the apnea-hypopnea index (AHI) using polysomnography results mild (5 ≤ AHI ≤ 15), moderate (15 < AHI ≤ 30), and severe OSAHS (AHI > 30), with 30 patients in each group. link3 Thirty sex- and age-matched healthy controls were recruited for this study. The serum levels of ApoB-100, FN, and CP were measured by enzyme-linked immunosorbent assays. dCA was assessed by analyzing the phase difference (PD) using transfer function analysis.

Serum levels of ApoB-100, FN, and CP were significantly higher in the mild, moderate, and severe OSAHS groups than that in the control group (

<0.001, respecti in patients with OSAHS. dCA was compromised in patients with OSAHS and was positively correlated with ApoB-100, FN, and CP serum levels, and FN serum levels and arousal index in polysomnography were independently associated with impaired dCA.

To explore the characteristics of gut microbiota and its relationship between clinical manifestations in patients with type 1 narcolepsy (NT1).

Scale and polysomnography were performed in 20 NT1 patients and 16 healthy controls (HC group) to evaluate the clinical characteristics of NT1. Illumina sequencing was performed on bacterial 16S ribosomal RNA gene using V3-V4 regions to compare the fecal microbiota in all subjects. Associations between clinical characteristics and gut microbiota were analyzed using partial correlation analysis.

Compared with the HC group, the NT1 group had a significantly higher ESS score, longer total sleep time, increased wakefulness, decreased sleep efficiency, disturbance of sleep structure, shorter mean sleep latency, and increased sleep-onset REM periods (all P < 0.05). No differences in alpha and beta diversity were observed between the two groups. In contrast, there were significant differences at the level of class, order, family, and genus (all P < 0.05). LEfSe analysis showed that the relative abundance of

in the NT1 group was higher than that in the HC group (P < 0.
