Squamous cell carcinoma of ear and temporal bone: A retrospective study on clinicopathological predictors.

Background: Ear and temporal bone squamous cell carcinoma (ETBSCC) is a rare and aggressive malignant tumor with minimal clinicopathological studies. The object of this study was to retrospectively evaluate the predictive effect of clinicopathological variables on the 5-year overall survival (OS) rate of ETBSCC patients in a single tertiary medical center in Tianjin, China.

Methods: A cohort of 44 patients with diagnosed ETBSCC from December 2012 to August 2022 were retrospectively studied.

Endocytosis-mediated entry of a caterpillar effector into plants is countered by Jasmonate.

Insects and pathogens release effectors into plant cells to weaken the host defense or immune response. While the imports of some bacterial and fungal effectors into plants have been previously characterized, the mechanisms of how caterpillar effectors enter plant cells remain a mystery. Using live cell imaging and real-time protein tracking, we show that HARP1, an effector from the oral secretions of cotton bollworm (Helicoverpa armigera), enters plant cells via protein-mediated endocytosis.

Retrospective analysis of clinical characteristics and related influencing factors of Kawasaki disease.

To compare the clinical characteristics of complete Kawasaki disease (KD) and incomplete Kawasaki disease (IKD), and analyze the possible risk factors of coronary artery lesion (CAL) in KD. The clinical data of 139 children with KD admitted to the hospital from January 2016 to June 2022 were analyzed retrospectively. The differences of clinical characteristics between children with KD and children with IKD were compared.

Clinical data analysis of 22 cases with hypoparathyroidism misdiagnosed as epilepsy.

Objective: Patients with hypoparathyroidism always present with recurrent tetany caused by hypocalcemia. These patients are usually misdiagnosed with epilepsy and incorrectly treated with anti-epileptic drugs. This research analyzed clinical data about 22 patients with hypoparathyroidism misdiagnosed as epilepsy and summarized the clinical experience for reducing misdiagnosis and incorrect therapy about hypoparathyroidism.

Kidney re-transplantation after living donor graft nephrectomy due to chromophobe renal cell carcinoma: A case report.

Background: There are few reported cases of allograft nephrectomy due to malignancy followed by successful renal re-transplantation two years later. In this paper, we report a patient who underwent kidney re-transplantation after living donor graft nephrectomy due to chromophobe renal cell carcinoma (ChRCC) involving the allograft kidney.

Case Summary: A 34-year-old man underwent living kidney transplantation at the age of 22 years for end-stage renal disease.

Crystal structure of 4-acetamido-benzoic acid monohydrate.

In the title compound, C9H9NO3·H2O, the plane of the acetamide group is oriented at 20.52 (8)° with respect to the benzene ring, whereas the plane of the carb-oxy-lic acid group is essentially coplanar with the benzene ring [maximum deviation = 0.033 (1) Å].

Crystal structure of tetraaquabis(8-chloro-9,10-dioxo-9,10-dihydroanthracene-1-carboxyl-ato-κO (1))cobalt(II) dihydrate.

In the title complex, [Co(C15H6ClO4)2(H2O)4]·2H2O, the Co(II) ion is bound by two carboxylate O atoms of two 5-chloro-9,10-anthra-quinone-1-carboxyl-ate anions and four water O atoms in a trans conformation, forming an irregular octa-hedral coordination geometry. This arrangement is stabilized by intra-molecular O-H⋯O hydrogen bonds between water and carboxyl-ate. Further O-H⋯O hydrogen bonds between coordinating and non-coordinating water and carboxyl-ate produce layers of mol-ecules that extend parallel to (001).

[Role of vasculogenic mimicry and endothelium-dependent vessel in metastasis of laryngeal cancer].

Objective: To investigate the contribution of vasculogenic mimicry (VM) and endothelium-dependent vessel (EDV) to invasion and metastasis of laryngeal squamous cell carcinoma (LSCC).

Methods: A total of 203 cases with LSCC was reviewed and followed up. VM and EDV in LSCC tissues were assessed by double staining with anti-CD31 immunohistochemistry and periodic acid-schiff.

[Effects of saltwater incursion on the microbiological characteristics and denitrification in a riparian rhizosphere soil in Chongming Island of Shanghai, East China].

A simulation test was conducted to study the effects of saltwater incursion on the microbiological characteristics and denitrification in the riparian rhizosphere soils vegetated with different plants in Chongming Island of Shanghai. Saltwater incursion changed the microflora in the rhizospheric soils. Except for actinomycete whose quantity had slight increase, the quantities of bacteria, fungi, nitrifiers, and denitrifiers all decreased to some extent by saltwater incursion, with the denitrifiers decreased by 51.

A pilot study on morphology and the mechanism involved in linearly patterned programmed cell necrosis in melanoma.

Accumulating data provide evidence that autophagy contributes to programmed cell death (PCD) under certain circumstances. Immunohistochemistry and real-time PCR were performed to investigate the correlation the expression of autophagy-related proteins LC3 and Atg4B and linearly patterned programmed cell necrosis (LPPCN) in melanoma. LPPCN was recently reported to be a special PCD, which is similar to neither apoptosis nor conventional necrosis commonly observed in tumoral tissues.

Temporal control of trichome distribution by microRNA156-targeted SPL genes in Arabidopsis thaliana.

The production and distribution of plant trichomes is temporally and spatially regulated. After entering into the flowering stage, Arabidopsis thaliana plants have progressively reduced numbers of trichomes on the inflorescence stem, and the floral organs are nearly glabrous. We show here that SQUAMOSA PROMOTER BINDING PROTEIN LIKE (SPL) genes, which define an endogenous flowering pathway and are targeted by microRNA 156 (miR156), temporally control the trichome distribution during flowering.

[Relationship between the expression of hypoxia-inducible factor-1alpha and epidermal growth factor receptor and micro vessel density and their clinical significance].

Objective: Analyze the relationship between the expression of hypoxia-inducible factor-1alpha (HIF-1alpha) and epidermal growth factor receptor (EGFR) and CD105 micro vessel density (MVD) and their value in evaluating biologic behavior and prognosis in laryngeal cancer.

Methods: Ninety-one cases of laryngeal cancer were analyzed about their clinical and pathology data. In tumor tissue the expression of HIF-1alpha and EGFR was detected by immunohistochemistry and MVD was marked by CD105.

Silencing a cotton bollworm P450 monooxygenase gene by plant-mediated RNAi impairs larval tolerance of gossypol.

We identify a cytochrome P450 gene (CYP6AE14) from cotton bollworm (Helicoverpa armigera), which permits this herbivore to tolerate otherwise inhibitory concentrations of the cotton metabolite, gossypol. CYP6AE14 is highly expressed in the midgut and its expression correlates with larval growth when gossypol is included in the diet. When larvae are fed plant material expressing double-stranded RNA (dsRNA) specific to CYP6AE14, levels of this transcript in the midgut decrease and larval growth is retarded.

[A clinico-pathological analysis of HCV infection in post-liver transplantation patients].

Objective: To investigate the pathological characteristics of HCV infection after liver transplantation.

Methods: This is a retrospective analysis of the clinico-pathological changes of 73 liver biopsies obtained from 61 patients who had HCV infection (including HCV recurrence and reinfection) after liver transplantation in our center from September 2000 to September 2006.

Results: Abnormal enzyme test results due to HCV infection happened on the 9th to the 1553rd post-transplantation surgery day.

Control of root cap formation by MicroRNA-targeted auxin response factors in Arabidopsis.

The plant root cap mediates the direction of root tip growth and protects internal cells. Root cap cells are continuously produced from distal stem cells, and the phytohormone auxin provides position information for root distal organization. Here, we identify the Arabidopsis thaliana auxin response factors ARF10 and ARF16, targeted by microRNA160 (miR160), as the controller of root cap cell formation.
