Published: September 2011

Background—
Women with familial hypercholesterolemia (FH) are prone to early cardiovascular disease and death. It is unknown whether FH adversely affects pregnant women and birth outcomes. We determined whether heterozygous FH women are at higher risk of premature birth (<37 gestational weeks), delivering children with low birth weight (<2500 g) and/or with congenital malformations compared to women in general.

Methods and Results—

We linked information from the Medical Genetics Laboratory with that of the Medical Birth Registry of Norway. We included 1869 FH women (≥14 years) from the Medical Genetics Laboratory and about 2 million (general population) from the Medical Birth Registry of Norway during the period 1967 to 2006. The registry match resulted in analysis of 2319 births of 1093 women with heterozygous FH. The mean (SD) prepregnancy total cholesterol concentration was 9.59 (2.06) mmol/L (370 [80 mg/dL]), whereas the concentration of total cholesterol was not available during pregnancy. The frequencies of prematurity, low birth weight, and congenital malformations for the 40-year period in the FH population were 6.8, 5.0, and 3.3, respectively. The corresponding values for the general population were 6.2, 5.2, and 3.2. The corresponding odds ratios were 1.11 (95 confidence interval 0.94–1.31;
P
=0.23), 0.96 (0.79–1.15;
P
=0.64), and 1.09 (0.87–1.37;
P
=0.45).

Conclusions—
Women with FH do not appear to have a higher risk of preterm delivery or of having infants with low birth weight or congenital malformations than women in general, but, although this is unlikely, some undetected bias may obscure the real differences.

Published: September 2011

Background: Cluster headache (CH) is a rare cause of headache in children. Onset before 12 years of age is unusual, and long-term follow-up of pediatric cases has been not reported. Objectives: To report three cases of CH with onset at childhood and at least ten years of follow-up. Methods: Case report. Results: The first case is that of a 12-year-old boy with episodic CH with unilateral pain and striking, bilateral autonomic manifestations, remitted for over eight years. The second case is unique in that it reports a case of chronic CH in a 13-year-old boy with Down syndrome. The third case is that of a 9-year-old girl with episodic CH with remissions of 2 and 5 years. All cases had prominent autonomic features. The frequency and duration of the attacks were similar to those that have been reported in adults. Good response to indomethacin was obtained in two cases, although tolerability issues occurred in one. Conclusion: Sustained, long-term, medical and/or spontaneous remission occurs in CH of early onset. The phenotype and response to therapy in children, at least in these case examples, are similar to equivalent observations in adult patients with CH.

Abstract

Background
In around 50% of all human cancers the tumor suppressor p53 is mutated. It is generally assumed that in the remaining tumors the wild-type p53 protein is functionally impaired. The two main inhibitors of p53, hMDM2 (MDM2) and hMDMX (MDMX/MDM4) are frequently overexpressed in wild-type p53 tumors. Whereas the main activity of hMDM2 is to degrade p53 protein, its close homolog hMDMX does not degrade p53, but it represses its transcriptional activity. Here we study the role of hMDMX in the neoplastic transformation of human fibroblasts and embryonic retinoblasts, since a high number of retinoblastomas contain elevated hMDMX levels.

Methods
We made use of an in vitro transformation model using a retroviral system of RNA interference and gene overexpression in primary human fibroblasts and embryonic retinoblasts. Consecutive knockdown of RB and p53, overexpression of SV40-small t, oncogenic HRasV12 and HA-hMDMX resulted in a number of stable cell lines representing different stages of the transformation process, enabling a comparison between loss of p53 and hMDMX overexpression. The cell lines were tested in various assays to assess their oncogenic potential.

Results
Both p53-knockdown and hMDMX overexpression accelerated proliferation and prevented growth suppression induced by introduction of oncogenic Ras, which was required for anchorage-independent growth and the ability to form tumors in vivo. Furthermore, we found that hMDMX overexpression represses basal p53 activity to some extent. Transformed fibroblasts with very high levels of hMDMX became largely resistant to the p53 reactivating drug Nutlin-3. The Nutlin-3 response of hMDMX transformed retinoblasts was intact and resembled that of retinoblastoma cell lines.

Conclusions
Our studies show that hMDMX has the essential properties of an oncogene. Its constitutive expression contributes to the oncogenic phenotype of transformed human cells. Its main function appears to be p53 inactivation. Therefore, developing new drugs targeting hMDMX is a valid approach to obtain new treatments for a subset of human tumors expressing wild-type p53.

Published: June 2024

Abstract3D printing of articular cartilage tissue faces challenges like replicating its complex structure, time‐consuming in vitro stem cell culture, and a lack of robust in situ regeneration methods for osteochondral defects (OC). In response, an innovative approach utilizing pre‐designed bioink modular units for one‐step printing and immediate implantation is proposed, circumventing the need for prior in vitro stem cell cultivation. The resulting printed scaffold not only accurately reproduces the three‐layer structure and material gradient of articular cartilage tissue but also attains impressive compressive strength (6.3 MPa) through the reinforcement of hydroxyapatite nanofibers and the establishment of chemical bonds with hydrogels. Moreover, the scaffold integrates stem cell capturing and homing layers on its bottom and top layers via chemical crosslinking aptamer and loading poly (lactic‐co‐glycolic acid) (PLGA) nanospheres encapsulated with stromal cell‐derived factor‐1α (SDF‐1α), respectively. This design enables the specific capture of bone marrow mesenchymal stem cells (BMSCs) in vivo through aptamer interaction, followed by their mobilization to home in on the hyaline cartilage layer via the chemotaxis of SDF‐1α concentration gradient. Within the scaffold's microenvironment, these BMSCs undergo differentiation into distinct cells for each layer, effectively contributing to the repair of OC defects in rabbits.

AbstractA poly(para)phenylene conjugated polymer is developed to store information via a quick and facile optical writing method. After exposure to UV light, co‐fluorescence (films with two or more written emission colors –, i.e., “double‐on”) and “on‐off” states are written into the flexible polymer films. The hidden information is invisible under ambient lighting and can only be read with an appropriate light source, optical filter, and/or magnifier, thus providing a level of security for information encoded into the films. The physical and chemical mechanisms are discussed responsible for the rapid fluorescence changes that occur under UV exposure and demonstrate microscale multi‐colored artwork and hidden QR codes written into pliable and freestanding films. Depending on the preparation, the written patterns remained easily visible and stable after exposure to water and to ambient levels of UV background radiation.

Published: June 2024

AbstractAnode‐free lithium metal batteries have attracted much attention due to their high energy density and lack of excess Li. In this work, Li film is deposited on large‐area copper foil (64 cm2) with good uniformity by a self‐designed electroplating device that quickly assembles and can be operated outside the glove box. By adding the high concentration of LiNO3 into the lithium bis(trifluoromethylsulfonyl)azanide (LiTFSI)‐based electrolyte, the high Li+ conductive solid electrolyte interface (SEI) layer regulated the Li+ flux, forming the columnar structure at a high current density of 40 mA cm−2, and compact morphology at 60 mA cm−2. Even at 100 mA cm−2, Li film on copper foil (Li@Cu) maintains its macroscopic uniformity. Furthermore, electrolytes, additives, and temperature are further optimized. The symmetric Li@Cu || Li cell cycle life can extend to 80 cycles. This work provides essential information for future manufacturing processes and scale‐up.

Published: June 2024

AbstractWe report herein a general one‐pot perfluoroalkylation/dehydrohalogenation protocol for the selective perfluoroalkenylation of silyl dienol ethers in their γ position. Importantly, this methodology is applicable to the synthesis of a wide range of γ‐perfluoroalkenylated enals, enones and α,β‐unsaturated amides. Various perfluoroalkenyl moieties could be efficiently introduced, with an important impact on the E/Z diatereoselectivity of the newly formed fluorinated double bond.

AbstractFood crop productivity is still low because of the decline of soil fertility in Ethiopia, particularly in north‐western Amhara. Fine‐tuning the source and rate of nutrients is required to solve soil fertility problems along landscape positions. Therefore, this study was initiated to investigate the need to apply selected nutrients to tef and wheat in acidic soils. This nutrient omission study was conducted in 74 farmers’ fields of Gozamen and Machakel districts. The omitted nutrients were sulfur (S), zinc (Zn), and boron (B). Potassium (K) was added, consisting of N, P, K, S, Zn, and B (All+K). Nitrogen plus phosphorus (NP) and no fertilizer treatments were used as positive and negative controls, respectively. Furthermore, 50% and 150% of the All+K treatments were also included. The finding revealed that the application of different nutrient types at variable rates had a significant role in the grain and biomass yield of both test crops in the acidic soils. No tef yield and the lowest yield of bread wheat were obtained from the no fertilizer application treatment. The application of All+K had no significant yield advantage compared to NP fertilizer alone. This implies that N and P are the most yield‐limiting nutrients to produce tef and bread wheat, whereas KSZnB nutrients are not yield limiting. Therefore, refining the rates of N and P in acidic soils is needed for the economical use of fertilizers. Finally, applying blended fertilizers without empirical evidence is not recommended for smallholder farmers in the study area.

Published: June 2024

AbstractBackgroundCannabidiol (CBD) products have increased in popularity in Japan in recent years, particularly among young people. Some CBD products contain tetrahydrocannabinol (THC), the main ingredient of cannabis, and its analogs, which are illegal in Japan and have become a social issue. This report discusses the safety of CBD products.Case PresentationFive patients with symptoms of CBD ingestion, including nausea, presented to our hospital. Three of the products these patients ingested contained THC. Metabolites of THC were detected in the blood and urine of all three patients, although there were some discrepancies in the urine drug screening test (DS10®). These examination results differed even when the same product was consumed.ConclusionCBD products are unsafe and may unintentionally contain THC. It is also important to understand that CBD can turn into THC, and the effective time needed to conduct urine drug screening.

Published: June 2024

New half‐sandwich dinuclear arene ruthenium complexes of the general formula [(η6‐p‐cymene)Ru(k2‐S‐arylthiourea)Cl] (1–3) have been synthesized. The structural characterization of the ruthenium complexes has been established using analytical and various spectroscopic techniques. The bidentate coordination of the ligands and pseudo‐octahedral geometry around the ruthenium(II) ion are confirmed by the single‐crystal X‐ray diffraction technique. In vitro antiproliferative activity of the complexes has been studied by MTT (3‐[4,5‐dimethylthiazol‐2‐yl]‐2,5 diphenyl tetrazolium bromide) assay against lung (A549), breast (MCF‐7), cervical (HeLa), ovarian (A2780) cancer cells, and non‐cancerous NIH‐3T3 mouse embryonic fibroblast cells. The results show that all the complexes exhibit excellent cytotoxicity towards all the cancer cells, with a low IC50 concentration compared with cisplatin. Further, the mode of cancer cell death has been examined by AO–EB (acridine orange/ethidium bromide), and DAPI (4',6‐diamidino‐2‐phenylindole) staining studies demonstrate the apoptosis‐associated cell morphological changes. Furthermore, the quantitative differentiation of late apoptosis has been elucidated by flow cytometry employing dual staining of Annexin V‐FITC and propidium iodide, which involves the transfer of phosphatidylserine to the external leaflet of the cytoplasmic membrane.
UV‐photopolymerized acrylic pressure‐sensitive adhesives with semi‐interpenetration structure: Effect of plasticizer structures on adhesion properties
Authors: Kim Misol , Kim Kyeongmin , Park Garam , Kim Hoon , Koo Jaseung 
Published: June 2024

AbstractAcrylic pressure‐sensitive adhesives (PSAs) were synthesized using a solvent‐free ultraviolet‐induced polymerization method. The monomers n‐(isobutoxymethyl) acrylamide, 2‐ethylhexyl acrylate, 2‐hydroxyethyl acrylate, and methyl methacrylate and an initiator, hydroxy dimethyl acetophenone, were used to prepare acrylic copolymers as prepolymers. A multifunctional monomer, trimethylolpropane triacrylate, was added to form a semi‐interpenetrating network, leading to an increase in the modulus and elasticity of the prepolymer. This decreased the peel strength, which is suitable for temporary protective films. Rheological data from small‐amplitude oscillatory shear measurements also revealed consistent results suitable for removable PSAs. The plasticizers, such as dioctyl phthalate and dioctyl terephthalate, possessing favorable interactions with the main resins were found to exhibit transparency, clear debonding, and ultralow release, which are essential features for temporary protective films.
Dynamic optimization of an integrated cultivation‐aggregation model for mAb production
Authors: Jones Wil , Gerogiorgis Dimitrios I. 
Published: June 2024

AbstractDue to their proteinaceous structure, monoclonal antibodies (mAbs) are susceptible to irreversible aggregation, with harmful consequences on drug efficacy and patient safety. To mitigate this risk in modern biopharmaceutical processes, it is critical to comply with current good manufacturing practices (cGMP) and pursue operating strategies minimizing irreversible aggregation whilst also maximizing mAb throughput. These conflicting objectives are targeted in this study by formulating and analyzing an integrated dynamic model accounting for both cultivation and aggregation of mAbs from a Chinese Hamster Ovary (CHO) cell line. Two manipulated dynamic variables are considered here in simulation studies: firstly temperature manipulation within a batch reactor, and secondly feed flow manipulation within a series of isothermal fed‐batch reactors. Following this, dynamic optimization investigations have been conducted, firstly with the single objective of maximizing mAb throughput and secondly with multiple (two) objectives of maximizing mAb throughput while also minimizing irreversible aggregate content, simultaneously. The study provides key insight into tradeoffs of how simultaneous temperature and feed flowrate manipulation affects mAb throughput and aggregation inside bioreactors.

Published: June 2024

AbstractBanisteriopsis (Malpighiaceae) is an important genus of neotropical savannas with related biological and medicinal activities but under‐explored metabolomic profiles. We present a chemometric analysis for discriminating secondary metabolites of three species of Banisteriopsis (B. laevifolia, B. malifolia, and B. stellaris) leaves. Initially, each species was separately extracted with ethanol:water (4 : 1, v/v) and analysed by Ultra Performance Liquid Chromatography coupled with Mass Spectrometry (UPLC‐MS/MS). The chromatographic profiles were subjected to Global Natural Product Social (GNPS) and Partial Least Squares Discriminant Analysis (PLS‐DA). Eighty‐nine compounds (cosine≥0.90) were annotated, including flavonoids, phenolics, and acids. The chemometric analysis (VIP Score) showed each species′ relative concentration of the more relevant compounds. In addition, four compounds that discriminate the metabolomic profiles of B. laevifolia, B. malifolia, and B. stellaris were identified by PLS‐DA.

Published: June 2024

Key Clinical MessageIn contrast to previously thought, arrhythmogenic cardiomyopathy can occur exclusively in the left ventricle in association with autosomal dominant mutation, even without any skin manifestations.AbstractWe present a case of a 43‐year‐old male with left ventricle (LV)‐predominant arrhythmogenic cardiomyopathy (ACM) caused by a novel p.Q1830 mutation in the desmoplakin (DSP) gene. The patient had a significant family history of sudden cardiac death (SCD) and presented with presyncope and exertional dyspnea. The patient's electrocardiography (ECG) showed frequent premature ventricular complexes (PVCs) with bigeminy and couplet patterns. Cardiac magnetic resonance imaging (CMR) revealed late gadolinium enhancement of the left ventricle (LV) and ventricular systolic dysfunction, suggesting LV‐predominant arrhythmogenic cardiomyopathy. The patient was started on guideline‐directed medical therapy (GDMT), and an implantable cardioverter‐defibrillator (ICD) was implanted for primary prevention. The patient reported significant improvement in his heart failure symptoms at the 2‐year follow‐up. The article highlights the importance of timely diagnosis with multimodality imaging and genetic testing and management of the rare DSP‐related LV‐predominant ACM associated with a high risk of SCD.

Published: June 2024

AbstractBioresorbable stents represent a revolutionary treatment for coronary artery disease. Such a device offers the prospect for complete naturalization of artery lumen after strut resorption and restoration of vasomotion while curtailing the duration of dual anti‐platelet therapy. The prototype bioresorbable scaffold (BRS—ABSORB GT1) demonstrated good feasibility and safety in the initial studies compared to metallic drug eluting stent but later fell out of favor due to multiple report of stent thrombosis and target lesion failure. Unpredictable resorption of struts turned out to be one of the “Achilles heel” of the BRS and stent strut were still visible in vessel on optical coherence tomography (OCT) at 3 years. We report a case of differential resorption of two ABSORB BRS implanted simultaneously in the same patient by the same operator. Follow up coronary angiogram revealed only minimal plaques on right coronary artery (RCA) and left anterior descending artery (LAD). The BRS were identified on cine‐angiogram by their radio‐opaque markers at both ends. The OCT run in LAD artery revealed “ghost remnants” of BRS struts in LAD, whereas the RCA BRS had completely healed with minimal “ghost” struts. The ghost remnants of BRS resembled the original “Check box” appearance on OCT during the index implantation.
