Breast cancer Auger electron therapy is a growing field of study in radioimmunotherapy and oncology research. Trastuzumab is a high affinity-binding monoclonal antibody against HER2/neu, which is overexpressed in breast tumors and used in radiopharmaceutical development.

In this work, the lethal effects of 111In3+, 111In-DTPA-trastuzumab, and 111In-trastuzumab coupled-nuclear localizing sequence peptide (111In-DTPA-NLS-trastuzumab) on malignant cells were studied in vitro.

DTPA-NLS-trastuzumab was prepared using sulfosuccinimidyl-4-(N-maleimidomethyl) cyclohexane-1-carboxylate (sulfo-SMCC) conjugation with NLS peptide in the first step, followed by conjugation with diethylenetriaminepentaacetic acid (DTPA). Both DTPA-trastuzumab and DTPA-NLS-trastuzumab were labeled with 111In, followed by purification and quality control techniques. Sk-Br-3 (a HER2/neu+ cell line) was used in the cell viability assessment assay for 11In, 111In-DTPA-trastuzumab, and 111In-DTPA-NLS-trastuzumab (3.7 MBq) at 37 ºC.

Among the various organic complications, albeit still little known, the gynecological implications, up to infertility, are very widespread. Among adolescent and adult patients, gynecological symptoms can be very widespread and range from menstrual irregularities to amenorrhea, from vaginitis to ovarian polycystosis, up to complications during the gestational phase and postpartum, in addition to the possible consequences on the unborn child. Among the most frequent and significant gynecological disorders in women with ED, there are menstrual irregularities that may occur with oligomenorrhea or even amenorrhea. , Although no longer part of the DSM-5 diagnostic criteria for defining anorexia nervosa (AN), this symptom must be considered a very relevant event in the overall evaluation of young women and adolescents with eating disorders. Functional hypothalamic amenorrhea in ED patients is related to psychological distress, excessive exercise, disordered eating, or a combination of these factors, which results in suppression of the hypothalamic-pituitary-ovarian axis, and consequently, hypoestrogenism. This paper has the objective to summarize the causes and the mechanism underlying menstrual disorders and provide a better understanding of the correlation between the reproductive system and the mechanisms that regulate food intake and eating habits. In addition, early recognition of risk factors for eating disorders for gynecological implications can help put more accurate assessments of patients to prevent potentially fatal complications. The importance of the involvement of specialist gynecologists in the multidisciplinary team that has to follow patients with eating disorders is also discussed.Alzheimer's disease (AD) is characterized by progressive memory loss due to neurodegeneration that occurs mainly during aging. The accumulation of senescent cells has been related to aging. Furthermore, the expression of the variant ApoE ∈ 4 is a critical risk factor for AD. Some events that occur in senescence, such as the secretion of pro-inflammatory molecules, and metabolic and epigenetic changes, in addition to the detection of ApoE4, may accelerate the progression of AD. Here, we discuss the implications of cellular senescence and the presence of ApoE polymorphisms in AD. Molecular studies of these risk factors for AD may hence be pivotal to define new biomarkers and novel therapeutic strategies for this neurodegenerative pathology.
TGF-β signaling pathway inhibition is considered an effective way to prevent the development of several diseases. In the design and synthesis of TGF-β inhibitors, a rhodanine compound containing a quinoxalinyl imidazole moiety was found to have strong antimicrobial activity.

The purpose of this work was to investigate the antimicrobial activity of other chiral rhodanine TGF-β inhibitors synthesized.

Two series of 3-substituted-5-((5-(6-methylpyridin-2-yl)-4-(quinoxalinyl-6-yl)- 1H-imidazol-2-yl)methylene)-2-thioxothiazolin-4-ones (12a-h and 13a-e) were synthesized and evaluated for their ALK5 inhibitory and antimicrobial activity. The structures were confirmed by their 1H NMR, 13C NMR, and HRMS spectra. All the synthesized compounds were screened against Gram-positive strains, Gram-negative strains, and fungi.

Among the synthesized compounds, compound 12h showed the highest activity (IC50 = 0.416 μM) against ALK5 kinase. Compound 12h exhibited a good selectivity index of > 24 against p38α MAP kinase and was 6.0-fold more selective than the clinical candidate, compound 2 (LY-2157299). Nearly all the compounds displayed high selectivity toward both Gram-positive and Gram-negative bacteria. They also showed similar or 2.0-fold greater antifungal activity (minimum inhibitory concentration [MIC] = 0.5 µg/mL) compared with the positive control compounds Gatifloxacin (MIC = 0.5 µg/mL) and fluconazole (MIC = 1 µg/mL).

The findings suggest that the synthesized rhodanine compounds have good ALK5 inhibitory activity and can be used for further research and development as potential antifungal drugs.

Nephrocolic fistula is a pathological connection between the kidney and colon. Percutaneous tumour ablation therapy is a rare cause of iatrogenic nephrocolic fistula in the literature.

Interventional radiologists should be careful, especially in patients with repeated ablation. Granulation of tissue may lead to unexpected results secondary to tissue fragility and impedance changes.

In addition, we should keep in mind that there is decreasing hydro dissection benefit in cases with the previous ablation. As far as we know, this is the first case report of an iatrogenic ephrocolic fistula after microwave ablation for recurrence renal cell carcinoma.
