Successful therapy using high-dose furmonertinib for non-small cell lung cancer with leptomeningeal metastasis: a case report and literature review.

Background: Lung cancer is the second most common form of malignant tumor and has the highest mortality rate worldwide. Among its subtypes, lung adenocarcinoma is the most prevalent. Leptomeningeal metastasis (LM) is rare and is characterized by a dismal prognosis, with overall survival periods typically spanning 4 to 6 weeks without treatment.

The involvement of abscisic acid-insensitive mutants in low phosphate stress responses during rhizosphere acidification, anthocyanin accumulation and Pi homeostasis in Arabidopsis.

Phosphorus is an essential plant nutrient, used in the formation of macromolecules such as nucleic acids and phospholipids. Abscisic acid (ABA) may be involved in the process of low inorganic phosphate (Pi) responses. The phenotypes of ABA-insensitive Arabidopsis mutants (abi1/2/3/4/5) under low Pi stress were investigated to identify possible low Pi response mutant genes.

Continuous Low-Dose Apatinib Combined With WBRT Significantly Reduces Peritumoral Edema and Enhances the Efficacy of Symptomatic Multiple Brain Metastases in NSCLC.

Background: Symptomatic multiple brain metastases with peritumoral brain edema (PTBE) occur in non-small cell lung cancer patients (NSCLC) who are without driver mutations or are resistant to epidermal growth factor tyrosine kinase (EGFR-TKI) are often associated with an unfavorable prognosis. Whole brain radiation therapy (WBRT) which comes with many complications and unsatisfactory effects, is the only option for the treatment. Previous studies have shown that bevacizumab can reduce the volume of PTBE and improve efficiency of radiotherapy.

Apatinib-induced Grade 3 hand-foot syndrome in advanced lung adenocarcinoma successful treated with thalidomide: A case report.

Hand-foot syndrome (HFS) is a specific cutaneous toxicity caused by a variety of antitumor drugs. The most common drugs include capecitabine, pegylated liposomal doxorubicin and fluorouracil (PLD), tyrosine kinase inhibitor. It is a dose-limiting cutaneous toxicity of these drugs.

The volume of Tc sulfur colloid SPET-defined active bone marrow can predict grade 3 or higher acute hematologic toxicity in locally advanced cervical cancer patients who receive chemoradiotherapy.

Background: The purpose of the current study was to evaluate whether radiation dose-volume metrics to technetium-99m ( Tc) sulfur colloid single-photon emission tomography (SPET)-defined active bone marrow (ABM) subregions can more accurately predict acute hematologic toxicity in locally advanced cervical cancer patients who receive chemoradiotherapy than conventional dosimetric parameters.

Methods And Materials: Thirty-nine patients with stage IB2-III cervical cancer who underwent Tc sulfur colloid SPET imaging before treatment with cisplatin-based chemoradiation between January 2017 and March 2018 were analyzed. The total bone marrow (TBM) volume was defined as the external contours of all bones within the vertebral bodies from L4 to the coccyx, the pelvic bones, and the proximal femoral heads.

Significant response of low-dose apatinib monotherapy in brain metastases of triple-negative breast cancer: A case report.

Rationale: The potential efficacy of apatinib in patients with advanced triple-negative breast cancer (TNBC) has been observed in a previous phase II clinical study. However, there is no study to evaluate its efficacy and safety in TNBC patients with brain metastasis (BM). Here we report one case that apatinib exhibited excellent antitumor effects in a breast cancer patient with brain metastasis, with no serious treatment-associated with adverse event.

Continuous use of metformin can improve survival in type 2 diabetic patients with ovarian cancer: A retrospective study.

Evidence indicates that type 2 diabetes may stimulate the initiation and progression of several types of cancer. Metformin, a drug most commonly used to treat type 2 diabetes, may inhibit cancer cell growth and reduce the risk of cancer. However, evidence of the antitumor effects of metformin on ovarian cancer is still limited.

miR156 modulates rhizosphere acidification in response to phosphate limitation in Arabidopsis.

Rhizosphere acidification is a general response to Pi deficiency, especially in dicotyledonous plants. However, the signaling pathway underlying this process is still unclear. Here, we demonstrate that miR156 is induced in the shoots and roots of wild type Arabidopsis plants during Pi starvation.

Modulation of the Phosphate-Deficient Responses by MicroRNA156 and its Targeted SQUAMOSA PROMOTER BINDING PROTEIN-LIKE 3 in Arabidopsis.

The microRNA156 (miR156)-modulated SQUAMOSA PROMOTER BINDING PROTEIN-LIKE (SPL) is involved in diverse biological processes that include growth, development and metabolism. Here, we report that the Arabidopsis miR156 and SPL3 as regulators play important roles in phosphate (Pi) deficiency response. MiR156 was induced during Pi starvation whereas SPL3 expression was repressed.

Eyelash trichomegaly following treatment with erlotinib in a non-small cell lung cancer patient: A case report and literature review.

Inhibitors of epidermal growth factor receptor (EGFR), including tyrosine kinase inhibitors (TKIs), present significant clinical benefits in the treatment of non-small cell lung cancer (NSCLC), particularly in patients with an EGFR mutation. However, TKI treatment also results in unwanted cutaneous toxic side effects, such as a skin rash. Eyelash trichomegaly is rarely reported as a side effect; however, it causes cosmetic issues or eyeball irritation in patients, which may result in the early termination of TKI treatment.

Transmembrane Topologies of Ca2+-permeable Mechanosensitive Channels MCA1 and MCA2 in Arabidopsis thaliana.

Sensing mechanical stresses, including touch, stretch, compression, and gravity, is crucial for growth and development in plants. A good mechanosensor candidate is the Ca(2+)-permeable mechanosensitive (MS) channel, the pore of which opens to permeate Ca(2+) in response to mechanical stresses. However, the structure-function relationships of plant MS channels are poorly understood.
