However, how animals respond to conspecific sounds when there is interference from environmental noise, and whether males and females display convergent behavioral responses in the face of noise masking remain poorly understood. In this study, we investigated the effects of conspecific male advertisement calls with different signal-to-noise ratios on male-male competition and female choice in the Anhui tree frog using playback and phonotaxis experiments, respectively.

At the same time, malaria has become a serious health concern for Chinese construction workers in Africa, who are at increased risk of infection and complications due to lack of immunity and exposure to high-transmission environments. One of the biggest challenges in fighting malaria is their lack of knowledge and misinterpretations about the disease, which can impact their need for interventions, adherence to treatments, and health services.

Objective: This study aimed to investigate the characteristics of microflora in patients with deep spinal surgical site infection (SSI) after prophylactic use of vancomycin powder (VP).
Methods: A retrospective analysis was performed on patients after spinal surgery.
BACKGROUND Epithelioid sarcoma is rare, represents less than 1% of all sarcomas, usually occurs in the extremities, and rarely presents as a primary sarcoma of the spine. Publications are usually single reports or case series. We aimed to undertake a systematic review of publications of cases of primary epithelioid sarcoma of the spine to evaluate clinical presentation, diagnosis, management, and patient outcomes.

Methods: The clinical data of 112 patients were retrospectively analyzed, and were divided into an MIS-TLIF group and OPEN-TLIF group. The operative time, intraoperative fluoroscopy, blood loss, postoperative drainage volume, bed rest time, the content of creatine kinase(CK) and complications, were recorded.

In China, the genus harbors many cryptic species, on two of which- and -studies were recently published. In this study, we collected specimens from the Dabie Mountain range, which is at the junction of Anhui, Henan and Hubei Provinces, East China; these specimens belonged to a species previously identified as .

Therefore, the search for superior direct Z-scheme photocatalysts is an urgent task. Herein, we predicted the WSeTe/ZrCO heterostructure as a potential direct Z-scheme photocatalyst based on density functional theory (DFT).

Methods: Thirty-two patients with degenerative scoliosis underwent long-segment posterior fixation were included. The spino-pelvic parameters were evaluated after surgery, and the HRQL scores were determined using the Scoliosis Research Society-22 (SRS-22), Oswestry Disability Index (ODI), and visual analog scale (VAS).

This paper proposes a novel floating high-voltage level shifter (FHV-LS) with the pre-storage technique for high speed and low deviation in propagation delay. With this technology, the transmission paths from input to output are optimized, and thus the propagation delay of the proposed FHV-LS is reduced to as low as the sub-nanosecond scale. To further reduce the propagation delay, a pull-up network with regulated strength is introduced to reduce the fall time, which is a crucial part of the propagation delay.

Methods: The following electronic databases were extensively searched from the inception of the database through December 2018: EMBASE, Medline, the Cochrane Library, and Web of Science. RCTs focusing on the outcomes of cemented and uncemented hemiarthroplasty were reviewed and screened for eligibility.
The Corneal wound healing results in the formation of opaque corneal scar. In fact, millions of people around the world suffer from corneal scars, leading to loss of vision. This study aimed to identify the key changes of gene expression in the formation of opaque corneal scar and provided potential biomarker candidates for clinical treatment and drug target discovery.

Many studies have reported that intra-arterial chemotherapy (IAC) combined with intravesical chemotherapy (IVC) could effectively reduce the recurrence rate of NMIBC. The purpose of this study is to assess the efficacy and safety of IAC combined with IVC for patients with high-risk NMIBC.
