The title compound, C14H19N2
+·BF4
−, was obtained by reaction of 1-ethyl-3-(2,4,6-trimethylphenyl)imidazolium tetrafluoroborate with sodium tetrafluoroborate. The imidazole ring makes a dihedral angle of 78.92 (13)° with the benzene ring
Florid cystitis glandularis (intestinal type) with mucus extravasation: Two case reports and literature review
BackgroundCystitis glandularis is a common bladder epithelial lesion characterized by hyperplasia and metaplasia of the bladder mucosa epithelium. The pathogenesis of cystitis glandularis of the intestinal type is unknown and less common. When cystitis glandularis (intestinal type) is extremely severely differentiated, it is called florid cystitis glandularis (the occurrence is extremely rare).Case summaryBoth patients were middle-aged men. In patient 1, the lesion was also seen in the posterior wall and was diagnosed more than 1 year ago as cystitis glandularis with urethral stricture. Patient 2 was examined for symptoms such as hematuria and was found to have an occupied bladder; both were treated surgically, and the postoperative pathology was diagnosed as florid cystitis glandularis (intestinal type), with mucus extravasation.ConclusionThe pathogenesis of cystitis glandularis (intestinal type) is unknown and less common. When cystitis glandularis of the intestinal type is extremely severely differentiated, we call it florid cystitis glandularis. It is more common in the bladder neck and trigone. The clinical manifestations are mainly symptoms of bladder irritation, or hematuria as the main complaint, which rarely leads to hydronephrosis. Imaging is nonspecific and the diagnosis depends on pathology. Surgical excision of the lesion is possible. Due to the malignant potential of cystitis glandularis of intestinal type, postoperative follow-up is required
Case Report: Adrenal glands degenerated schwannoma: Report of three cases and literature review
BackgroundSchwannoma is a benign tumor, of which degenerated schwannoma is a subtype. Retroperitoneal schwannomas are extremely rare, as they account for only 3% of retroperitoneal tumors.Degenerated schwannoma is a schwannoma subtype. However,degenerated schwannoma occurring in the adrenal glands is extremely rare.Case summaryCase 1: A 42-year-old man was referred to our hospital for further examination of a left adrenal mass that was incidentally discovered during a routine physical check-up.No significant abnormalities were found in laboratory tests results. Robotic-assisted laparoscopic excision of the left adrenal gland was performed under general anesthesia. Case 2: A 47-year-old man was admitted to the hospital because of a left adrenal mass found on a routine physical examination.The patient was previously in good health, and there was no family history of a similar disorder. Left-sided laparoscopic adrenalectomy was performed under general anaesthesia. Case 3: A 62-year-old woman with hypertension and diabetes mellitus was referred to our hospital after an incidentally found left adrenal mass.There was no family history of a similar disorder. Left-sided laparoscopic adrenalectomy was performed under general anaesthesia. None of the patients had a recurrence in our study during the postoperative follow-up.ConclusionDegenerated schwannoma of the adrenal glands is very rare. The clinical presentations of degenerated schwannoma are nonspecific; a small number of patients do not have any symptoms, and the mass is only found incidentally during physical examination for any number of reasons. The preoperative diagnosis of adrenal degenerated schwannoma is difficult because the diagnosis must rely on pathological examination and immunohistochemistry assays. The management is surgical excision and regular follow-up
A panther chameleon skin-inspired core@shell supramolecular hydrogel with spatially organized multi-luminogens enables programmable color change
Organization of different iridophores into a core@shell structure constitutes an evolutionary novelty for panther chameleons that allows their skins to display diverse color change. Inspired by this natural color-changing design, we present a responsive core@shell-structured multi-luminogen supramolecular hydrogel system that generates a programmable multi-color fluorescent change. Specifically, red Eu-amidopicolinate (R) luminogen is incorporated into the core hydrogel, while blue naphthalimide (B) and green perylene-tetracarboxylic acid (G) luminogens are grown into two supramolecular shell hydrogels. The intensities of G/B luminogens could then be controlled independently, which enables its emission color to be programmed easily from red to blue or green, nearly covering the full visible spectrum. Because of the differential excitation energies between these luminogens, a desirable excitation wavelength-dependent fluorescence is also achieved. Colorful materials with a patterned core@shell structure are also demonstrated for anti-counterfeiting, opening up the possibility of utilizing a bioinspired core@shell structure to develop an efficient multi-color fluorescent system with versatile uses
Case report: Rudimentary uterine horn with ovarian endometriosis manifested as pelvic ectopic kidney
BackgroundUnicornuate uterus is a congenital uterine malformation. Unicornuate uterus with rudimentary horn, ovarian endometriosis, and congenital renal agenesis are rare combinations that can be easily misdiagnosed due to the lack of typical clinical manifestations.Case summaryA 19-year-old woman with pelvic pain was admitted to the hospital after a month. Physical examination was unremarkable. B-ultrasound and CT scan both indicated pelvic ectopic kidney. In addition, renal scintigraphy revealed normal perfusion and function of the right kidney, but the perfusion and function of the left kidney were not visible. A left pelvic ectopic kidney was diagnosed by preoperative images. A laparoscopic left pelvic ectopic nephrectomy was performed after adequate surgical preparation. However, the postoperative pathological diagnosis revealed a rudimentary uterine horn with ovarian endometriosis and congenital renal agenesis. Fortunately, she got recovered and was discharged from the hospital after 5 days following the operation. Moreover, she received regular follow-ups at the gynecology clinic. To date, no right adnexal or uterine abnormalities have been detected on ultrasound during the follow-up visits.ConclusionRudimentary uterine horn with ovarian endometriosis and congenital renal agenesis are rare and are easily Misdiagnosed due to the lack of typical clinical manifestations. A gynecological examination is recommended for patients who may have this disease
Dynamics of transcriptome changes during subcutaneous preadipocyte differentiation in ducks
Pekin duck is an important animal model for its ability for fat synthesis and deposition. However, transcriptional dynamic regulation of adipose differentiation driven by complex signal cascades remains largely unexplored in this model. This study aimed to explore adipogenic transcriptional dynamics before (proliferation) and after (differentiation) initial preadipocyte differentiation in ducks.https://doi.org/10.1186/s12864-019-6055-
Adjustment of Prescription by ORAC assay to Enhance the Effect of Medicinal Liqueur
Objective: The ingredient herbs of JING liqueur were studied, and prescription was adjusted by oxygen radical absorbance capacity (ORAC) assay to enhance the effect of this medicinal liqueur. Method: Values of very herb's ORAC were measured, the proportions of high ORAC value herbs were increased, while the proportions of low ORAC value herbs were decreased. Adjusted JING liqueur was compared with primary product by the test of anti-fatigue and enhance immunity experiment. Result: Compared with primary product, the anti-fatigue effect of adjusted JING liqueur was significantly increased, and the enhance immunity effect of adjusted JING liqueur was obviously improved. Conclusion: The effect of JING liqueur could enhanced by adjust proportions of every ingredients across their ORAC, increased the proportions of high ORAC value herb could obviously improved the anti-fatigue and enhance immunity efficacy
