Unusual outbreaks of curly top disease in processing tomato fields in northern California in 2021 and 2022 were caused by a rare strain of beet curly top virus and facilitated by extreme weather events.

In the western United States, curly top disease (CTD) is caused by beet curly top virus (BCTV). In California, CTD causes economic loss to processing tomato production in central and southern areas but, historically, not in the north. Here, we document unusual CTD outbreaks in processing tomato fields in the northern production area in 2021 and 2022, and show that these were caused by the rare spinach curly top strain (BCTV-SpCT).

Acupuncture treatment for lumbar disc herniation with scoliosis: A case report.

Introduction: Lumbar disc herniation (LDH) with scoliosis usually refers to lumbar disc herniation caused by scoliosis, which is a postural compensatory deformity to reduce low back and leg pain, mostly with nonstructural changes. Scoliosis may disappear after the treatment of LDH.

Patient Concerns: At present, this kind of scoliosis is mainly treated with medicine and surgery, but all these methods may have some adverse effects.

TBUnet: A Pure Convolutional U-Net Capable of Multifaceted Feature Extraction for Medical Image Segmentation.

Many current medical image segmentation methods utilize convolutional neural networks (CNNs), with some extended U-Net-based networks relying on deep feature representations to achieve satisfactory results. However, due to the limited receptive fields of convolutional architectures, they are unable to explicitly model the varying range dependencies present in medical images. Recently, advancements in large kernel convolution have allowed for the extraction of a wider range of low frequency information, making this task more achievable.

The aim of this study is to explore the influence of MAFLD on the complications after hepatectomy in patients with hepatitis B virus-related hepatocellular carcinoma (HBV-HCC).

Theoretical study on ferroelectric nitrides with super-wurtzite structures for solar energy conversion applications.

Polarized structured nitride semiconductors are attractive due to their unique and environment-friendly electronic properties. The stability, ferroelectricity and photocatalytic and photovoltaic properties of super-wurtzite MgXN (X = Bi, Mo, Nb, Sb, Ta, Tc and W) were determined based on first principles calculations in this study. The calculated results indicate that MgXN (X = Sb, Ta, Bi and Nb) are stable polar nitrides by phonon frequencies, elastic coefficients and ferroelectric analysis.

Curly Top Disease of Hemp () in California Is Caused by Mild-Type Strains of Often in Mixed Infection.

Interest in industrial hemp () as a potential crop led to the establishment of commercial fields in a number of counties in California in 2019 and 2020. Plants in these fields developed different types of virus-like symptoms. The most prevalent type was stunted and bushy plants with distorted, upcurled, and yellowed leaves, which were similar to those associated with curly top disease (CTD) caused by the beet curly top virus (BCTV).

Background: Metabolic dysfunction-associated fatty liver disease (MAFLD) is recently proposed an entity by a group of international experts. However, the impact of MAFLD on the prognosis of patients with hepatocellular carcinoma (HCC) is not clear. The aim of this study was to explore the influence of MAFLD for the prognosis of HCC after radical resection.

Development of an IPM Strategy for Thrips and in Processing Tomatoes in the Central Valley of California.

(TSWV; species ; genus ; family ) is a thrips-transmitted virus that can cause substantial economic losses to many crops, including tomato (). Since 2005, TSWV emerged as an economically important virus of processing tomatoes in the Central Valley of California, in part due to increased populations of the primary thrips vector, western flower thrips (WFT; ). To develop an understanding of the epidemiology of TSWV in this region, population densities of WFT and incidence of TSWV were monitored in California's processing tomato transplant-producing greenhouses and associated open fields from 2007 to 2013.

Post-traumatic stress disorder (PTSD) is a serious psychiatric disorder. Estazolam has been shown to produce anxiolytic-, hypnotic-, amnestic-, and sedative-like effects. However, few studies are concerned about its anti-PTSD-like effects.

The anxiolytic-like effects of ginsenoside Rg3 on chronic unpredictable stress in rats.

The present study is to evaluate the anxiolytic-like activities underlying ginsenoside Rg3 (GRg3). The anxiolytic-like activities were induced by GRg3 (20 and 40 mg/kg, i.g), evidenced by blocking the decreased time and entries in the open arms in elevated plus maze test and by reversing the increased latency to feed in novelty-suppressed feeding test.

Targeting microbubbles-carrying TGFβ1 inhibitor combined with ultrasound sonication induce BBB/BTB disruption to enhance nanomedicine treatment for brain tumors.

The clinical application of chemotherapy for brain cancer tumors remains a challenge due to difficulties in the transport of therapeutic agents across the blood-brain barrier/blood-tumor barrier (BBB/BTB). In this study, we developed des-octanoyl ghrelin-conjugated microbubbles (GMB) loaded with TGFβ1 inhibitor (LY364947) (GMBL) to induce BBB/BTB disruption for ultrasound (US) sonication with GMBL. The in-vitro stability study showed that GMB was pretty stable over one month.

Preservation of viral genomes in 700-y-old caribou feces from a subarctic ice patch.

Viruses preserved in ancient materials provide snapshots of past viral diversity and a means to trace viral evolution through time. Here, we use a metagenomics approach to identify filterable and nuclease-resistant nucleic acids preserved in 700-y-old caribou feces frozen in a permanent ice patch. We were able to recover and characterize two viruses in replicated experiments performed in two different laboratories: a small circular DNA viral genome (ancient caribou feces associated virus, or aCFV) and a partial RNA viral genome (Ancient Northwest Territories cripavirus, or aNCV).

Background: The chronic shortage of nursing staffs in hospitals continues to increasingly and negatively impact the ability of medical care systems to deliver effective care and ensure the safety of patients. Bullying is one factor known to exacerbate turnover in the nursing workplace.

Purpose: This study explores workplace bullying and turnover intention among nurses working at a medical center in Southern Taiwan.

[Achievements and enlightenment of modern acupuncture therapy for stroke based on the neuroanatomy].

Up to now, in the treatment of stroke patients by acupuncture therapy, three main representative achievements involving scalp acupuncture intervention, "Xing Nao Kai Qiao" (restoring consciousness and inducing resuscitation) acupuncture technique and nape acupuncture therapy have been got. Regarding their neurobiological mechanisms, the scalp acupuncture therapy is based on the functional localization of the cerebral cortex, "Xing Nao Kai Qiao" acupuncture therapy is closely related to nerve stem stimulation, and the nape acupuncture therapy is based on the nerve innervation of the regional neck-nape area in obtaining therapeutic effects. In fact, effects of these three acupuncture interventions are all closely associated with the modern neuroanatomy.

Polymersomes conjugated with des-octanoyl ghrelin and folate as a BBB-penetrating cancer cell-targeting delivery system.

Chemotherapy for brain cancer tumors remains a big challenge for clinical medicine due to the inability to transport sufficient drug across the blood-brain barrier (BBB) and the poor penetration of drug into the tumors. To effectively treat brain tumors and reduce side effects on normal tissues, both des-octanoyl ghrelin and folate conjugated with polymersomal doxorubicin (GFP-D) was developed in this study to help transport across the BBB and target the tumor as well. The size measurements revealed that this BBB-penetrating cancer cell-targeting GFP-D was about 85 nm.

Polymersomes conjugated with des-octanoyl ghrelin for the delivery of therapeutic and imaging agents into brain tissues.

The effective protection of the blood-brain barrier (BBB) from tight junctions and efflux transport systems ultimately results in the limited entry of 95% of drug/gene candidates, which are potentially beneficial for central nervous system (CNS) diseases. In order to enhance the brain-specific delivery, in this study we developed a targeting carrier system, which consists of poly(carboxyl ethylene glycol-g-glutamate)-co-poly(distearin-g-glutamate) (CPEGGM-PDSGM) polymersomes with the conjugation of des-octanoyl ghrelin. Des-octanoyl ghrelin across the BBB was reported to be unidirectional (blood-to-brain direction).
