Our case report describes a patient where multiple laparoscopies five years from initial presentation of symptoms were performed prior to laparotomy for benign multi-cystic peritoneal mesothelioma (BMPM), which has not been documented.

A 61-year-old woman presented with years of chronic abdominal pain. Computerized tomography (CT) demonstrated a multi-cystic mass near the porta hepatis, and ultrasound was concerning for contained gallbladder perforation. Fine needle aspiration (FNA) demonstrated benign ductal epithelial cells in a background of mucin and bile without the presence of malignant cells. During laparotomy, a cystic mass attached to the porta hepatis seen emanating from the small bowel mesentery, and additional small cystic lesions through the abdomen were removed. The specimen, measuring 26 × 18 × 8 cm, showed multi-loculated cysts filled with serous fluid.

BMPM is a rare neoplasm of mesothelioma cells originating from serosa of viscous organs. BMPMs appear as cystic structures with thin walls containing mucinous/gelatinous fluid. Microscopic features include a lack of invasion and no increased cellularity in the stroma, with or without inflammation (Myers & Babiker, 2018). It is postulated to be either a reactive or neoplastic process. There is no gold-standard treatment for BMPM. Our case is unique in the sense that our patient required several surgical biopsies before final diagnosis could be made.

This case highlights the difficulty of diagnosing BMPM and differentiating it from malignant diseases that can present similarly and can be associated with significantly worse prognosis. link2 Defined management strategies have yet to be demonstrated.

Renal cell carcinoma (RCC) arises from the renal parenchyma and is the most common primary malignancy of the kidney. RCC frequently metastasizes to the lung, bone, lymph nodes, and other locations, but rarely to the colon. We report a case of metastatic RCC of the ascending colon that was successfully resected with laparoscopic right hemicolectomy.

The patient is a 65-year-old man who developed hip joint pain and was diagnosed with polymyalgia rheumatica during the first year after laparoscopic right nephrectomy for right RCC. A screening colonoscopy was performed and a tumor was found in the ascending colon. Biopsy strongly suggested metastatic RCC. No other distant metastases were found, and laparoscopic right hemicolectomy was performed. The tumor extended from the mucosa to the subserosa and was diagnosed histopathologically as colonic metastasis of RCC. There were no lymph node metastases in the simultaneously resected mesentery, but venous invasion was observed.

RCC can metastasize to various organs, but metastasis to the colon is extremely rare. In cases of colon metastasis, abdominal symptoms, hematochezia, or anemia may occur, and their occurrence should be checked during follow-up. Based on past reports, resection of metastatic lesion is considered the most appropriate treatment.

Although it is rare for RCC to metastasize to the colon, it is possible. Resection can be recommended for colon metastasis with no other metastases, and colectomy with R0, including the regional mesocolon, may provide a favorable long-term prognosis.

The first method was chemometric methods applied were PLS-1, GA-PLS and GA-ANN. To compare the prediction ability of the models, a 4-factor 5-level experimental design was used to establish a calibration set of 25 mixtures containing different ratios of the drugs and their degradation products. The validity of the proposed methods was assessed using an independent validation set of 5 mixtures. The comparison between the different models showed the superiority of ANN model in solving the highly overlapped spectrh those obtained by applying the reported method.
Survival of patients with stage III colon cancer varies widely according to T-N sub-stages. Estimating the benefit of each therapeutic option in each T-N subgroupmay provide more accurate information helping doctors and patients in the complex shared decision-making process surrounding adjuvant therapy.

The outcomes data of 12,834 patients with stage III colon cancer enrolled in the IDEA trial served as our database. Patients were categorised in 16 sub-stages, based on T-N categories. We created a meta-regression model to predict the expected 5-year DFS within each T-N sub-stage. We then evaluated the efficacy of each therapeutic option in every sub-stage, working backward by subtraction, using an average of the HRs reported in pertinent trialpublications as a conversion factor.

Large differences in 5-year DFS rate were observed among the subgroups, ranging from 89% (T1N1a) to 31% (T4N2b) in the overall population. The contribution to the outcome of each therapeutic option in this setting varied widely across sub-stages. According to our model, patients with T1N1a cancers have a projected 5-year DFS of 79.6% with surgery alone. Adjuvant fluoropyrimidine alone results in 5.6% absolute DFS gain; an additional 2.3% and 0.8% gain is seen with oxaliplatin for 3 and 6 months, respectively. Patients with T4N2b cancers show a 13.9% 5-year DFS with surgery alone, and an 11.2%, 6.4%, 2.5% increase with the aforementioned adjuvant options, respectively.

The resulting overlay bar graph gives patients and doctors the projected relative benefit of each treatment option and may substantially help the shared decision-making process, although caution must be exercised in using this model due to the significant variance of the estimates.

Blood lead level (BLL) is the routine measure used for diagnosing the degree of lead intoxication, although it is unclear whether there is any safe range of BLL. To develop a practical detection tool for living organisms, we engineered a genetically encoded fluorescence resonance energy transfer (FRET)-based Pb2+ biosensor, 'Met-lead 1.44 M1', with excellent performance. Met-lead 1.44 M1 has an apparent dissociation constant (Kd) of 25.97 nM, a detection limit (LOD) of 10 nM (2.0 ppb/0.2 μg/dL), and an enhancement dynamic ratio of nearly ~ 5-fold upon Pb2+ binding. The 10 nM sensitivity of Met-lead 1.44 M1 is five times below the World Health Organization-permitted level of lead in tap water (10 ppb; WHO, 2017), and fifteen times lower than the maximum BLL for children (3 μg/dL). We deployed Met-lead 1.44 M1 to measure Pb2+ concentrations in different living models, including two general human cell lines and one specific line, induced pluripotent stem cell (iPSC)-derived cardiomyocytes, as well as in widely used model species in plant (Arabidopsis thaliana) and animal (Drosophila melanogaster) research. Our results suggest that this new biosensor is suitable for lead toxicological research in vitro and in vivo, and will pave the way toward potential applications for both low BLL measures and rapid detection of environmental lead in its divalent form.The diagnosis of tumor metastasis using circulating tumor cells (CTCs) has been considered an important developmental target for several decades but remains a formidable challenge because of the rarity and heterogeneity of CTCs. Additional downstream analysis is required after isolating CTCs on-chip for subtype verification. To solve those problems, we have developed microfluidic based integrated system which uses magnetic field gradient and immune-fluorescence differences to on-chip isolation and discrimination of CTCs simultaneously. link3 The system presented in the present study can isolate CTCs with an efficiency of >99% by utilizing magnetic nanoparticles conjugated to CTC membranes. Furthermore, the statuses of three biomarkers can be determined on-chip simultaneously. The devised microfluidic system can differentiate eight different subtypes of heterogenic CTCs by on-chip isolation and based on the statuses of three biomarkers (HER2, ER, and PR) which are critical variables to five-year overall survivals for breast cancer patients.Photocathodic bioassays have shown great potential to apply in real bio-sample detection owning to their intrinsic abilities against interference from reductive species. However, the pursuit of photocathodic bioassays with excellent detection performance is still in the infancy. Herein, an advanced signal amplifier of platinum-based nanocatalyst with efficient oxygen reduction capability was explored to build a high-performance photocathodic immunoassay. The target model of carbohydrate antigen 19-9 (CA19-9, Ag) was used for describing the sensing platform. Specifically, the nontoxic Au/CuBi2O4 photocathode was first prepared by decorating Au nanoparticles on CuBi2O4 nanofilm and was used as the matrix to anchor capture CA19-9 antibody (Ab1). Platinum (Pt) nanoparticles were loaded on graphene (GR) nanosheet to form Pt/GR nanocomposite, which was utilized as signal amplifier conjugating with signal CA19-9 antibody (Ab2). When specific sandwich immunoreaction happened, the Pt/GR played the role of an efficient nanocatalyst to accelerate the reduction reaction of electron acceptor of oxygen in the electrolyte, causing evidently enhanced cathodic photocurrent signal. By incorporating this superior signal amplification strategy into the anti-interference photocathodic immunoassay, highly sensitive and specific detection of target Ag was realized. This work pioneers a new perspective for the design of advanced photocathodic bioanalysis for various targets of interest.
