Artificial intelligence (AI) for tumor microenvironment (TME) and tumor budding (TB) identification in colorectal cancer (CRC) patients: A systematic review.

Evaluation of the parameters such as tumor microenvironment (TME) and tumor budding (TB) is one of the most important steps in colorectal cancer (CRC) diagnosis and cancer development prognosis. In recent years, artificial intelligence (AI) has been successfully used to solve such problems. In this paper, we summarize the latest data on the use of artificial intelligence to predict tumor microenvironment and tumor budding in histological scans of patients with colorectal cancer.

Comparative Clinical and Histomorphologic Evaluation of the Effectiveness of Combined Use of Calcium Hydroxyapatite and Hyaluronic Acid Fillers for Aesthetic Indications.

Hyaluronic acid and calcium hydroxylapatite (CaHA) have been used for in the field of soft tissue augmentation. Both materials have been used in combination to enhance tissue remodeling and provide a more rejuvenated look. Sequential injections of Belotero Volume (CPM-HA V) and CaHA had a relatively greater remodeling effect on one's skin compared with the simultaneous injections of CPM-HA V and CaHA.

Photodynamic therapy of lung cancer with photosensitizers based on polycationic derivatives of synthetic bacteriochlorin (experimental study).

Background: One of the tasks of anticancer photodynamic therapy is increasing the efficacy of treatment of cancer nodes with large (clinically relevant) sizes using near-infrared photosensitizers (PS).

Methods: The anticancer efficacy and mechanisms of the photodynamic action of PS based on polycationic derivatives of synthetic bacteriochlorin against Lewis lung carcinoma were studied in vitro and in vivo.

Results: It was found that studied PS have high phototoxicity against Lewis lung carcinoma cells: the IC values were about 0.

Antitumor activity of photodynamic therapy with tetracationic derivative of synthetic bacteriochlorin in spheroid culture of liver and colon cancer cells.

Efficient screening of photosensitizers (PS) as well as studying their photodynamic activity, especially PS excited in the near-infrared region, require informative in vitro models to adequately reflect the architecture, thickness, and intercellular interactions in tumors. In our study, we used spheroids formed from human colon cancer HCT-116 cells and liver cancer Huh7 cells to assess the phototoxicity of a new PS based on tetracationic derivative of synthetic bacteriochlorin (BC4). We optimized conditions for the irradiation regime based on the kinetics of BC4 accumulation in spheroids and kinetics of spheroid growth.

Primary Undifferentiated Pericardial Sarcoma after Radiоtherapy for Hodgkin Lymphoma.

Various types of sarcomas arise as a result of postradiation chronic fibrous pericarditis. A primary undifferentiated spindle cell pericardial sarcoma is a rare type of sarcoma after radiotherapy. The risk of sarcoma increases with time after treatment of cancer.

Immunomorphological Features of the Placenta in Allogeneic Pregnancy as the Background for the Development of Obstetric Complications.

Objective: To study the structural and immunohistochemical features of placentas in women after assisted reproductive technology (ART) with allogeneic eggs (oocyte donation and surrogate motherhood).

Study Design: The study involved 89 women whose pregnancy occurred as a result of in vitro fertilization (IVF) with a donor egg in a surrogate motherhood program (IVF-SM, n = 47 patients) or oocyte donation (IVF-DO, n = 42). The comparison group consisted of 21 patients in whom pregnancy occurred as a result of IVF with their own egg (IVF-OE).

Combination of Calcium Hydroxylapatite Diluted With Normal Saline and Microfocused Ultrasound With Visualization for Skin Tightening.

Background/Objectives: Treatment options for the correction of age-related changes in skin include the use of energy-based devices and dermal fillers. In this study, we evaluate the clinical efficacy and tolerability of microfocused ultrasound with visualization (MFU-V) and injectable calcium hydroxylapatite (CaHA) filler diluted with normal saline, for the correction of age-related changes and to assess patients' satisfaction with this combination therapy. Methods: This was a randomized, split-face, comparative clinical study and immunohistochemical analysis in 20 subjects with indications for lower face, neck and décolleté lifting.

Improved Neocollagenesis and Skin Mechanical Properties After Injection of Diluted Calcium Hydroxylapatite in the Neck and Décolletage:A Pilot Study.

Background: Calcium hydroxylapatite (CaHA; Radiesse (R)) provides safe and effective correction of moderate-to-deep lines, volume replacement, lift and contour, and induction of neocollagenesis and neoelastogenesis for improved skin quality. CaHA hyperdilution takes advantage of its skin-tightening properties without a volumizing effect.

Objective: To evaluate the collagen- and elastin-stimulating effects of diluted CaHA in subjects with skin laxity in the neck and décolletage.
