Prelithiation is a critical step in dual carbon lithium-ion capacitors (LICs) due to the lack of Li in the system, which needs to be incorporated externally to avoid electrolyte depletion. Several prelithiation techniques have been developed over the years, and recently, dilithium squarate (LiCO) has been reported as an air-stable, easy to synthesize, safe, and cost-effective prelithiation reagent for LICs. LiCO has successfully been used in a wide range of chemistries, and its integration into positive electrodes has been scaled up to roll-to-roll processing and demonstrated in multilayer pouch cells.

This work studies the use of epoxy and polyurethane formulations as binders for the aqueous processing of activated carbon (AC) electrodes used as positive and negative electrodes in Electrochemical Double Layer Capacitors (EDLCs). The use of amine and carbodiimide as crosslinkers is also evaluated. The mechanical properties of those different binders have been investigated, looking towards aqueous processable and flexible electrodes.

Platelet-rich plasma (PRP) is an autologous biologic product used in several fields of medicine for tissue repair due to the regenerative capacity of the biomolecules of its formulation. PRP consists of a plasma with a platelet concentration higher than basal levels but with basal levels of any biomolecules present out of the platelets. Plasma contains extraplatelet biomolecules known to enhance its regenerative properties.

Background: Surgery and stereotactic body radiotherapy (SBRT) are two of the options available as local treatments for pulmonary oligometastases from colorectal cancer (CRC). We hypothesized that SBRT would have, at least, a similar local control rate to surgery.

Methods: We identified an initial cohort of 100 patients with CRC who received SBRT or surgery for lung metastases.

Leprosy is a chronic, neglected tropical infectious disease, currently endemic in Formosa, a province in northwestern Argentina. To analyze the performance, distribution, and effectiveness of the health system in leprosy diagnosis in Formosa, we estimated the trend of the number of new cases of leprosy diagnosed between 2002 and 2019 and estimated a forecast for 2022 at the primary health care centers (PHCCs) of at the first level of care (1stLC), at district hospitals (DHs) of the second level of care (2ndLC), high-complexity hospitals at the third level of care (3rdLC), and in rural and urban areas. The general trend was calculated based on the new cases detection rate (NCDR) using the autoregressive-moving average model (ARMA).

Background: The province of Formosa, Argentina, is endemic for leprosy. In the present paper, we assessed the trend (T, 2002-2016 time series) and the forecast for 2022 of new case detection rate (NCDR) and determined the spatial distribution of new cases detected (NCD) of leprosy.

Methodology/principal Findings: This is a descriptive observational study of 713 NCD of leprosy from provincial medical records between January 2002 and December 2016.

Background: Diabetes is related with increased cancer mortality across multiple cancer types. Its role in lung cancer mortality is still unclear. We aim to determine the prognostic value of fasting plasma glucose (FPG) and diabetes mellitus in patients with locally advanced non-small cell lung cancer (NSCLC) treated with concurrent chemoradiotherapy.

Background: Although concurrent chemoradiotherapy (cCRT) increases survival in patients with inoperable, locally advanced non-small-cell lung cancer (NSCLC), there is no consensus on the treatment of elderly patients. The aim of this study was to determine the prognostic value of the comprehensive geriatric assessment (CGA) and its ability to predict toxicity in this setting.

Methods: We enrolled 85 consecutive elderly (⩾75 years) participants, who underwent CGA and the Vulnerable Elders Survey (VES-13).

Background: Corrientes, a province of northeastern Argentina with endemic leprosy, has improved its epidemiological indicators, however, a study of the dynamics over time is lacking.

Objectives: We analysed data of 1308 leprosy patients between 1991 to 2014, and the forecast for 2020.

Methods: Descriptive statistics and stepwise Bayesian model selection were performed.

Establishing the putative links between sylvatic and domestic transmission cycles of Trypanosoma cruzi, the etiological agent of Chagas disease, is of public health relevance. We conducted three surveys to assess T. cruzi infection in wild mammals from a rural and a preserved area in Misiones Province, Northeastern Argentina, which had recently been declared free of vector- and blood-borne transmission of human T.

Objectives: The long-term impact of stereotactic body radiotherapy (SBRT) on respiratory function in patients with inoperable non-small cell lung cancer (NSCLC) has not been well studied. The aim of this phase II trial was to assess local control, survival, and lung function at 36 months after treatment.

Methods: From July 2008 to February 2012, 42 patients in whom inoperable NSCLC with peripheral lesions was diagnosed were consecutively enrolled.

The optimal schedule and regimen of chemotherapy (CT) in association with chemoradiation has not been established in stage III non-small-cell lung cancer (NSCLC). We have compared three schedules of non-platinum-based CT plus either radiotherapy or chemoradiation. From May 2001 to June 2006, 158 patients with unresectable stage III NSCLC were enrolled in a randomized phase II trial with overall response rate (ORR) as the primary endpoint.

Purpose: Although concurrent chemotherapy and radiation is the standard approach for good risk unresectable stage III non-small cell lung cancer (NSCLC) patients, there is no optimal concurrent chemotherapy regimen. Administration of chemotherapy at full dose with maximal activity against local and micrometastatic disease is highly desirable. This study tested the feasibility of 3 cycles of full dose cisplatin and pemetrexed concurrent with definitive thoracic radiotherapy followed by consolidation pemetrexed, without the dose-limiting toxicity (DLT) exceeding 33% of the patients.

Despite the strong immune responses elicited after natural infection with Trypanosoma cruzi or vaccination against it, parasite survival suggests that these responses are insufficient or inherently inadequate. T. cruzi contains a major cystein proteinase, cruzipain, which has a catalytic N-terminal domain and a C-terminal extension.

Trypanosoma cruzi, the agent of Chagas disease contains a major cysteine proteinase, cruzipain (Cz), with an unusual carboxyl-terminal extension (C-T). We have previously reported the presence of sulfate groups in the N-linked oligosaccharide chains of this domain. In order to evaluate the immune responses to sulfated moieties on Cz, BALB/c mice were immunized with purified Cz and C-T prior and after desulfation treatment.

Background: Radiation therapy (RT) alone is frequently used in elderly patients with medically inoperable early stage (I/II) non-small cell lung cancer (NSCLC). We retrospectively investigated the effectiveness of RT alone in this patient population treated in our institution.

Material And Methods: Between 1995 and 1999, a total of 33 patients were treated with RT alone in our institution, all being males.

Expression and activity of matrix metalloproteinase-9 (MMP-9) as well as its relationship with hyaluronan (HA) and NF-kappaB activity were analyzed in two murine lymphoma cell lines with dissimilar migration and invasive behavior. MMP activity was evaluated by zymograms in supernatants, membrane extracts of tumor cells, and in the organs invaded by these cells. The more aggressive LBLa cell line showed MMP-9 activity in vitro, which increased after HA treatment and was blocked by anti-CD44 mAb.

Chagasic cardiomyopathy is a major life-threatening complication of Trypanosoma cruzi infection in human beings. This study focuses on the hypertrophic and hyperplastic mechanisms underlying the structural changes of the heart during experimental infection. Proliferating cell nuclear antigen (PCNA) expression, transversal diameter, nuclear area, and number of nuclei per unit volume were determined in the ventricular myocytes of T.
