Near-infrared (NIR) fluorescence imaging with a novel fluorophore: ZW800-1

Kim S de Valk; Marion M Deken; Maxime JM van der Valk; Alexander L Vahrmeijer

European Journal of Molecular & Clinical Medicine, 2019, Volume 6, Issue 1, Pages 1-2

Intraoperative near-infrared (NIR) fluorescence imaging is a novel technique that combines the use of a fluorescent agent with a dedicated near-infrared camera system, to allow real-time visualization of lymph nodes, tumor tissue and/or vital anatomic structures for surgical guidance (Vahrmeijer et al. 2013). NIR light ranges in the wavelength of 700- 900 nanometers, is invisible to the naked eye and can only be detected with dedicated NIR imaging systems, which are currently available from various commercial companies. Fluorescent agents are mainly administered intravenously at a given time prior or during surgery, in order to enable realtime imaging during the procedure. The time of injection is dependent on the biodistribution of the specific agent. After injection the fluorescent agent is cleared by either the liver or kidneys and accumulates in the target (i.e. lymph node, tumor or vital structure) by either physiological processes (enhanced permeability and retention effect), specific targeting or through their clearance route.

Aim: We aimed to investigate the action mechanism of Zhengyuan capsule (a registered proprietary Chinese medicine) against chemotherapy-related fatigue (CRF). Methods: BALB/c-nu nude mice model with human lung adenocarcinoma A549 xenografts was constructed by injection of A549 cell suspension. The xenografted mice were randomly divided into model, cisplatin and cisplatin+Zhengyuan groups (n = 20 each). The cisplatin group was given an intraperitoneal injection of 5 mg/kg cisplatin every 3 days for 21 days. The cisplatin+Zhengyuan group was given an intragastric administration of cisplatin and 25 mg/kg Zhengyuan capsule each day for 21 days. Normal control and model groups were administrated with equal amount of saline. Forced swimming assay, tail suspension test, open field test, hepatic glycogen assay, blood analysis, and bone marrow smear was performed. Results: The cisplatin group developed CRF after receiving chemotherapy. When compared with cisplatin group, the cisplatin+Zhengyuan group exhibited longer exhaustive swimming time (p

Totally Extra-Peritoneal (TEP) laparoscopic ventral hernia and incisional hernia repair: Reverse TEP (r-TEP)

European Journal of Molecular & Clinical Medicine, 2019, Volume 6, Issue 1, Pages 12-13

Laparoscopic ventral hernia and incisional hernia repair has now become a standard technique. However, the disadvantage of this technique is the contact between the mesh and tacks and the viscera. The objective of this article is to describe totally laparoscopic extra-peritoneal ventral and incisional hernia repair to avoid this problem. We developed a reverse Dulucq’s technique for laparoscopic inguinal hernia repair described as Reverse Totally Laparoscopic Extra-Peritoneal ventral hernia repair (R-TEP).

Aim: The aim of this study was to analyse the expression at the mRNA level of cytochromeb, subunits COI, COII, COIII of complex IV, ATP6 and ATP8 and to perform aquantitative analysis of the activity of ATP synthase as complex V of the respiratory chain, responsible for ATP synthesis and break down of ATP to ADP in breast cancer. Methods and Results: The level of gene expression at the mRNA level was evaluated on the basis of the light intensity of fluorochrome or fluorescein in the cells. Determination of the activity and location of the ATP synthase in cells was carried out using hybridization. In the formulations of breast cancer there was a higher genes expression at the mRNA level for all the examined genes as compared with non-cancerous tissue. The ATP activity was also higher in preparations obtained from breast cancer cells compared with the control tissue. Conclusions: The results confirm mtDNA incorporation to nDNA in neoplastic cells. They point to increased expression at mRNA level for COI, COII, COIII, ATP6 and ATP8 in breast cancer cells compared with control tissue. Increased amount of ATP synthase points to increased ATP in a neoplastic cell.

There are many clinical evidences that hyperuricemia is a risk factor for the development of peripheral carotid and coronary vascular diseases. However, the mechanism of elevated uric acid concentration in biological systems is not yet clear. In the present work Fourier transform infrared (FT-IR) spectroscopy was used to evaluate the mechanism of calcification and plaque formation in carotid arteries in hyperuricaemic patients. Comparison between the spectra of carotid arteries from patients with elevated uric acid values and spectra obtained from patients with normal uric acid values showed structural changes of the characteristic spectral bands in the region 4000-500 cm-1. These changes were related with changes in the concentration of the serum uric acid and the clinical history of the patients. The intensity decrease of the infrared bands in the region 1650-1500 cm-1 was associated with the decrease of the apolipoprotein ratio, ApoI/ApoII, which corresponds to HDL (High Density Lipoproteins) and the regulation of the LDL (Low Density Lipoproteins), which are related to oxidation stress. The infrared band at 1467 cm-1 indicated the presence of urea components as a result of the metabolic pathway. The shape and the intensity of the bands between 1250-900 cm-1 depend on the glycation-end products of the diseases. SEM-EDX chemical analysis showed fibril formation and molybdenum release in hyperuricaemic patients.

The mechanisms and challenges of cancer chemotherapy resistance: A current overview

European Journal of Molecular & Clinical Medicine, 2019, Volume 6, Issue 1, Pages 26-34

Chemotherapy remains one of the principal modes of treatment for cancer patients. Despite advances in anticancer agents for multiple cancers, development of resistance to classical chemotherapeutic drugs and targeted drugs continues to be a major challenge. Drug resistance which can be either intrinsic or acquired, leads to treatment failure and tumor progression. Drug resistance occurs because of mechanisms that are associated with individual cancer cells or through mechanisms that relate to the microenvironment within tumors. Multiple molecular determinants of intrinsic and acquired resistance including genetic, epigenetic factors, as well as other factors which act at the genomic or cellular level have been identified. This review provides a conspectus on some of the recent discoveries on mechanisms of anticancer drug resistance and the possible ways to revert resistance and thereby improve cancer therapy.

European Journal of Molecular & Clinical Medicine, 2019, Volume 6, Issue 1, Pages 35-49

Barbiturates are derivative of barbituric acid which acts as central nervous system
depressant. The primary detection of barbiturates is carried out by the presumptive tests
viz. Dille Koppanyi test and Zwikker’s test. A comparative study was done in order to
determine whether there are any differences in the results of the two tests and to find out
the test with more consistency. Drug samples containing Phenobarbital viz. Gardenal-30
and Gardenal-60 were used in the study. Solution mixtures of 9 different ratios were
prepared in the ratios 1:9, 2:8, 3:7, 4:6, 5:5, 6:4, 7:3, 8:2 and 9:1 comprising stock solution
of Phenobarbital and solvent (Methanol AR). Both the tests were performed upon the
samples at different proportions on spot tile and test tubes and the absorbance values
(given by UV/VIS Spectrophotometer) for all the various test results at different
concentrations were compared. The study demonstrated that Dille-Koppanyi test showed
better results after interpretation of the absorbance values using Independent sample ‘t’
test and Coefficient of variation. A mean value of 2.85 was found for Zwikker’s test and a
mean value of 3.19 for Dille-Koppanyi test. A significant difference of p<0.01 was obtained
between the results from the two tests. Further, a better consistency was found from the
absorbance values of Dille-Koppanyi test as compared to the absorbance values of
Zwikker’s test which is shown by the values of Coefficient of variation that was found to be
higher for Zwikker’s test (2.00 and 5.86 for Gardenal-30 and Gardenal-60 respectively)
and lower for Dille-Koppanyi test (0.78 and 2.26 for Gardenal-30 and Gardenal-60
respectively). In cases of trace amounts of drug sample being recovered from crime scene
suspected to be barbiturate, primary detection can be efficiently done directly using Dille-
Koppanyi test instead of Zwikker’s test which will lead to a better outcome in the

European Journal of Molecular & Clinical Medicine, 2019, Volume 6, Issue 1, Pages 81-90

Tumor budding is the histological phenomenon seen as a detached, discohesive small cluster
of cells in the invasive tumor front. Tumor buds may provide a histological means for the
assessment of epithelial-mesenchymal interaction and facilitate early prediction of
prognosis.The present study aims to assess the prognostic significance of the tumor budding in
oral squamous cell carcinoma(OSCC). Detailed Histopathological scoring of the oral
squamous cell carcinoma tissue and lymph nodes including the evaluation of tumor budding
was performed by two individual observers retrospectively. The association between various
clinicopathological parameters and the budding index was analyzed using chi-square test and
fisher’s exact tests. Tumor budding was demonstrated in the invasive tumor front of all OSCC
cases. High-intensity tumor budding was seen in stage 4 cancers with tumor size of > 4cms.
Histologically, they were related to deep and extensive tumors, having an invasive front with
infiltrative cells in groups or cords, dense stromal type in association with mild inflammation
invariably. All of the cases with lymph node metastases were tumor budding positive. Thus this
study emphasizes the importance of tumor budding evaluation in regular pathology practice in
the management of OSCC cases.

The Internet of Things is the notion of linking any gadget to the Internet and other
connected devices (provided that it has an On/Off switch). It is a gigantic network of linked
objects and people – all collecting and sharing information about their use and the
surrounding environment. This includes an extraordinary number of items in all shapes
and sizes – ranging from smart microwaves that automatically cook your food for the
proper time period to self-driven cars whose complex sensors detect objects along their
path, to wearable fitness equipment that measure your cardiac velocity and the number of
steps taken on that day. There are even linked footboards that can track how far and
quickly they are being thrown and recorded for future training reasons using an
application. By taking advantage of major Bluetooth vulnerabilities, a cybersecurity expert
pirated a Tesla Model X in less than 90 seconds. For identical reasons, other automobiles
using FOB (wireless) keys have undergone assaults to open and start their automobiles.
Threat actors have identified a technique of scanning and replicating the interface of these
FOB keys to rob the corresponding cars with no alarm. If high-tech machines such as a
Tesla are exposed to an IoT data leak, every smart device is vulnerable to it.

Elderly person of 80 years of age and older presents a specific challenge to anesthetists,
who needs toacquire and maintain skill and expertise in the management of such patients.
Departments should havea lead clinician with an interest in the care of the elderly.
Development in anesthesia and operative techniques hasconsiderably reduced morbidity
and mortality in the elderly patients.Several anesthetic techniques have been used for
elderly patientsincluding general anesthesia, regional anesthesia, intravenoussedation and
monitored anesthesia care. However, anesthesiarelatedmortality in these patients is still
high. All elderly patientsundergoing surgical procedures require a preprocedural
evaluationto assess the risks of anesthesia and procedure and to manageproblems related
to the preexisting medical conditions, monitoringpatients during intraprocedural and
postprocedural periods aswell as postprocedural management. This article considers
theage-related physiological changes, preprocedure assessmentand preparation, anesthetic
techniques, intraoperative care andpostoperative care. Age does not obtund the perception
of pain. Acute and chronic pain management teams should be available totreat the elderly.
Prophylaxis for Thrombo embolic disease should initiated to prevent further complications.
