Scars of the Past – Stories: Creating A Short Story Collection Highlighting Childhood Emotional Neglect and Its Impacts in Adulthood
Authors: Rahardjo Winona Nathania , Irawan Stefanny
Published: March 2024

Childhood Emotional Neglect (CEN) is described as a parent’s failure to respond enough to their child’s emotional needs. Although the effects can be severe, it is rarely studied compared to other kinds of childhood abuse and maltreatment. The writers hope to raise awareness about the topic through a short story collection which consists of four stories. Each story shows different types of emotionally neglectful parents, its impacts on the victims as adults, and how they overcome their situation using Dr. Jonice Webb’s empirical insights on CEN as a theoretical framework. The protagonists: Amanda, Brian, Christine, and Daniel, are people in their early twenties who go through their lives trying to deal with the impact of childhood emotional neglect that their parents gave them. The stories show a few types of emotionally neglectful parents: the combination of the narcissistic parent and the achievement/perfection focused parent, the permissive parent, the workaholic parent, and child as parent. The impacts in adulthood materialize in these stories include hiding emotions and lack of self-love, lack of self-discipline, lack of self-esteem, and being overly responsible. The solutions pursued by the main characters are learning to say no, improving their sense of self-discipline, self-soothing, and trying to put themselves first.
Errors on Sentence Structures Made by Students in Writing 2 and Writing 4 Classes
Authors: Octaviani Manuela , Wijaya Henny Putri Saking
Published: March 2024

This study analyzed the types of errors on sentence structures by students in Writing 2 and Writing 4 classes in the English Department, Petra Christian University, and their similarities and differences. Eight categories of common errors on sentence structures proposed by Ho (2005) were used to analyze thedrafts. The types of common errors in this study were limited to four: Run-on Sentence, Fragmented Sentence, Inappropriate Subordinate Conjunction, and Misordering. The findings showed that both classes made all types of the errors and the most common error made was run-on sentences in the form of comma splice. Fragmented sentences with missing verb and subject were only found on writing 2 drafts while subordinating clauses in fragmented sentences were found on writing 4 drafts. Moreover, errors in relation to subordinating conjunction were more prominent in Writing 4. In conclusion, difficulties in utilizing conjunctions, and the different complexity of the drafts might affect the errors on sentence structures.

In translating, difficulties often emerge during the translation process. In translating the book entitled Hidden Potential written by Wendy Pope from English to Bahasa Indonesia, Mona Baker’s translation strategies are used to overcome the difficulties that emerge in the translation process. The strategies used are as follows: translation by a more general word, translation by a more neutral word, translation by cultural translation, and translation by omission. The strategy of translation by illustration is not used since this book contains only words without any pictures or illustrations.
Here Comes The Sun: A Novel Portraying Quarter-life Crisis of a College Graduate
Authors: Jordan Jeremy , Setiawan Dwi
Published: March 2024

Quarter-life crisis (QLC) is a period of uncertainty and questioning that typically occurs when people feel trapped, uninspired, and disillusioned during their mid-20s to early 30s, which is the currently most discussed and concerning topic nowadays since this issue is causing problems in twenty-somethings. Using the Quarter-life Crisis theory, this thesis explores the symptoms, causes, and solutions of QLC. Using psychological realism as its genre, this novel will explore the interior life of the main character, Rei, who experiences QLC. This novel tells the story of Rei, a fresh graduate who is unemployed for six months and is pressured by his father, under the influence of societal structure, to look for a job. Through the story, it can be seen that Rei’s symptoms of QLC are anxiety, identity crisis, and depression. The causes of his QLC are high expectations from his surroundings, sudden responsibility changes, and self-doubt. Solutions to his QLC are acknowledging his own QLC, asking for help, and accepting himself.
Thorns Covered in Petals on a Pedestal: A Collection of Lyrical Poetry Exploring the Cause and Effects of Toxic Female Friendship¬
Authors: Sachi Hsie Michiko , Limanta Liem Satya
Published: March 2024

When a female friend envies and covets what her female friend has, this leads to a toxic female friendship. Toxicity among female friends has its effects on the victims. This leads the victim to normalize toxic friendship behavior, experience loneliness, and have lower self-worth compared to people who are not the victim of the said phenomenon. This creative work is written in a collection of lyrical poetry, portraying the cause and effects of toxic female friendship. There are fifteen poems in total, with six poems portraying the perpetrator’s envy (‘PART I: Side-eyes on Shiny Emblems’) and another nine poems expressing loneliness and lower self-worth of the victim (‘PART II: Lone to the Bone, Too Gloom to Bloom’). This creative work, ‘Thorns Covered in Petals up on a Pedestal’ shows how vicious a hint of envy can be, thus the terrible outcomes it brings in a friendship among females, especially to the victim.

The economic burden of carpal tunnel syndrome: Long‐term earnings of CTS claimants in Washington State
Authors: Foley Michael , Silverstein Barbara , Polissar Nayak
Published: January 2007

Background

The long‐term earnings losses borne by injured workers, beyond those covered by workers' compensation insurance, are rarely estimated. The post‐claim earnings of a cohort of carpal tunnel syndrome (CTS) claimants are tracked over a period of 6 years and compared to the earnings of claimants with either upper extremity fractures or dermatitis.

Methods

Quarterly earnings records of 4,443 workers in Washington State who filed claims with the State Fund in 1993 or 1994 for CTS are compared to those of 2,544 with upper‐extremity fracture claims and 1,773 with medical‐only dermatitis claims. Multivariate regression was used to identify the effect of injury type on earnings from that of other potential predictors.

Results

CTS claimants recover to about half of their pre‐injury earnings level relative to that of comparison groups after 6 years; they also endured periods on time‐loss three times longer than claimants with upper extremity fractures. CTS surgery claimants had better outcomes than those who did not have surgery. Earnings recovery fractions among CTS claimants were better for workers who: (1) were younger; (2) had stable pre‐claim employment; (3) lived in the Puget sound area; (4) worked for large businesses; (5) worked in non‐construction/transportation industries; or (6) were in the higher pre‐injury earnings categories. Cumulative excess loss of earnings of the 4,443 CTS claimants was $197 million to $382 million over 6 years, a loss of $45,000–$89,000 per claimant. This underscores the importance of prevention, early diagnosis, and accommodation for return to work. Am. J. Ind. Med. 50: 155–172, 2007. © 2007 Wiley‐Liss, Inc.
Synergistic antiglioma activity of radiotherapy and enzastaurin
Authors: Tabatabai Ghazaleh , Frank Brigitte , Wick Antje , Lemke Dieter , von Kürthy Gabriele , Obermüller Ulrike , Heckl Stefan , Christ Gunter , Weller Michael , Wick Wolfgang
Published: January 2007

Objective

Radiotherapy is an essential treatment modality for malignant gliomas, but it exerts adverse effects via promotion of glioma cell invasion in experimental glioma. Furthermore, irradiation induces vascular endothelial growth factor (VEGF) levels in gliomas, which is associated with poor prognosis. Here, we investigate the combination of the protein kinase C‐β inhibitor enzastaurin (ENZA) and radiotherapy in vitro and in vivo in comparison with either treatment alone.

Methods

We analyzed the effects of ENZA and irradiation on migration, apoptosis, and proliferation of glioma cells, as well as VEGF secretion in vitro. Neurotoxicity of ENZA was assessed in cerebellar granule neurons. After orthotopic intracerebral implantation of LNT‐229 glioma cells in nude mice, the effects of in situ cerebral irradiation and oral application of ENZA on survival, tumor size, VEGF expression, apoptosis, and microvessel density in vivo were analyzed.

Results

Combining cerebral irradiation with ENZA leads to longer survival in vivo. ENZA diminishes tumor volume, irradiation‐induced tumor satellite formation, upregulation of VEGF expression in vitro and in vivo, as well as enhanced microvessel density in vivo. Importantly, ENZA is not neurotoxic in vitro or in vivo.

Interpretation

Long‐term administration of ENZA after radiotherapy is feasible and leads to long‐term survival without neurotoxicity. Ann Neurol 2007

Published: January 2007

Muskeln können chemische Energie in mechanische Arbeit umsetzen. Zur Entwicklung künstlicher Muskeln eignen sich weiche Materialien mit hoher mechanischer Flexibilität und Lebensdauer besser als harte Materialien wie Metalle. Für wirksame muskelähnliche Bewegungen sollten die Materialien Schichtstrukturen und einen hohen molekularen Ordnungsgrad aufweisen. Flüssigkristalline Elastomere (liquid‐crystalline elastomers, LCE) sind diesbezüglich überlegene weiche Materialien, die die Ordnung von Flüssigkristallen und – da sie Polymernetzwerke enthalten – die Elastizität von Elastomeren in sich vereinen. Mit LCEs lassen sich kleine Mengen externer Energie in makroskopisch messbare mechanische Arbeit umwandeln. In diesem Aufsatz konzentrieren wir uns auf Licht als Energiequelle und beschreiben die neuesten Fortschritte auf dem Gebiet weicher Materialien, die Licht direkt in mechanische Arbeit umwandeln können (photomechanischer Effekt), insbesondere die photomechanischen Effekte von LCEs unter dem Blickwinkel der Anwendungsentwicklung lichtgetriebener Aktuatoren.

In insects, developmental responses are organ‐ and tissue‐specific. In previous studies of insect midgut cells in primary tissue cultures, growth‐promoting and differentiation factors were identified from the growth media, hemolymph, and fat body. Recently, it was determined that the mitogenic effect of a Manduca sexta fat body extract on midgut stem cells of Heliothis virescens was due to the presence of monomeric α‐arylphorin. Here we report that in primary midgut cell cultures, this same arylphorin stimulates stem cell proliferation in the lepidopterans M. sexta and Spodoptera littoralis, and in the beetle Leptinotarsa decemlineata. Studies using S. littoralis cells confirm that the mitogenic effect is due to free α‐arylphorin subunits. In addition, feeding artificial diets containing arylphorin increased the growth rates of several insect species. When tested against continuous cell lines, including some with midgut and fat body origins, arylphorin had no effect; however, a cell line derived from Lymantria dispar fat body grew more rapidly in medium containing a chymotryptic digest of arylphorin.

Maternal flu or fever, medication use, and neural tube defects: A population‐based case‐control study in Northern China
Authors: Li Zhiwen , Ren Aiguo , Liu Jianmeng , Pei Lijun , Zhang Le , Guo Zhanying , Li Zhu
Published: January 2007

BACKGROUND: Maternal exposure to flu or fever has been associated with increased risk for neural tube defects (NTDs); however, few studies have considered the effects of medications on the effects of flu or fever. We evaluated the effect of maternal flu or fever, medication use (antibiotics, antipyretics), and their joint effect on NTDs. METHODS: Data came from an ongoing population‐based case‐control study of infants with external malformations in northern China. The case group included 363 infants with NTDs identified between January 2003 and June 2005. Controls were 523 newborn infants without identified congenital anomalies matched by county, sex, maternal ethnic group, and the closest date of conception for infants with any major external malformation. Data were collected by a trained health worker through face‐to‐face interviews after delivery. RESULTS: NTD risks were significantly associated with maternal flu or fever (adjusted odds ratio [AOR] = 3.93, 95% CI: 2.48–6.23) and antipyretic use (AOR = 4.86, 95% CI: 1.33–17.78), but not with antibiotic use (AOR = 1.75, 95% CI: 0.91–3.38) after adjusting for potential confounders. NTD risk associated with maternal antipyretic use was markedly higher for anencephaly (AOR = 7.03, 95% CI: 1.70–29.04) than for spina bifida (AOR = 3.98, 95% CI: 0.95–16.74). Mothers with flu or fever who were also using antipyretics showed a markedly higher AOR for anencephaly (14.75 vs. 4.52), spina bifida (16.30 vs. 3.85), and all NTDs combined (13.91 vs. 4.04) than mothers with flu or fever who were not using antipyretics. Maternal antibiotics did not markedly change the effects of flu or fever on anencephaly (4.17 vs. 4.83), spina bifida (5.08 vs. 4.21), and all NTDs combined (5.05 vs. 4.29). CONCLUSIONS: Maternal flu or fever and antipyretic use during the periconceptional period increases the risk for NTDs. Maternal exposure to antipyretics together with flu or fever results in a markedly higher risk of NTDs than exposure to flu or fever alone.

Fmoc‐based solid‐phase synthesis of GPR54‐agonistic pentapeptide derivatives containing alkene‐ and fluoroalkene‐dipeptide isosteres
Authors: Tomita Kenji , Narumi Tetsuo , Niida Ayumu , Oishi Shinya , Ohno Hiroaki , Fujii Nobutaka
Published: January 2007

Fmoc‐protected Phe‐Gly‐type (Z)‐alkene dipeptide isostere (ADI) and (E)‐fluoroalkene dipeptide isostere (FADI) were synthesized and applied to Fmoc‐based solid‐phase peptide synthesis (SPPS). These cis‐peptide bond mimetics were introduced into a bioactive pentapeptide [H‐Amb‐Phe‐Gly‐Leu‐Arg‐Trp‐NH2; Amb = 4‐(aminomethyl) benzoic acid], which has potent GPR54 agonistic activity. The resulting pentapeptide derivatives showed low GPR54 agonistic activity, as compared with the parent peptide and (E)‐ADI‐containing derivative. This suggests that the trans‐amide conformer of Phe‐Gly peptide bond of the parent peptide would be significantly important for bioactivity. Contrary to our expectations, a (Z)‐FADI‐containing derivative exhibited essentially no activity, revealing the necessity of critical validation of FADI‐bioisosterism. © 2007 Wiley Periodicals, Inc.

Leptin acts as a mitogenic and antiapoptotic factor for colonic cancer cells
Authors: Hoda M R , Keely S J , Bertelsen L S , Junger W G , Dharmasena D , Barrett K E
Published: January 2007

Background

Obesity is associated with increased levels of leptin. The mitogenic actions of leptin have been identified in various cell types. Because obesity may be a risk factor for colonic cancer, the proliferative and antiapoptotic effects of leptin on colonic cancer cells and the role of mitogen-activated protein kinase (MAPK) and phosphatidylinositol 3-kinase (PI3-K) signalling were investigated.

Methods

Three human colonic cancer cell lines (T84, HT29/Cl.19A and Caco-2) were treated with leptin. Cell proliferation was measured using the XTT® colorimetric assay and apoptosis by a cell death enzyme-linked immunosorbent assay. Inhibitors of MAPK and PI3-K were used to evaluate the role of these signalling pathways. Phosphorylation of the downstream components extracellular signal-regulated kinase (ERK) 1/2 and Akt was detected by western blotting.

Results

Leptin increased cell number in all cell lines in a dose-dependent manner and reduced the number of apoptotic cells in a cell line-dependent manner. Leptin also caused ERK1/2 and Akt phosphorylation. Pretreatment with inhibitors of MAPK and PI3-K inhibited these responses, attenuated the mitogenic action of leptin and abolished its antiapoptotic effects.

Conclusion

Chronic increases in leptin concentration may enhance the growth of colonic cancers via MAPK and PI3-K pathways. These effects of leptin could provide a link between obesity and colonic cancer, and may represent a target for anticancer drug development.

The cover picture shows an imaging study of a cytotoxic small molecule AA005, which is able to recognize and enter human cancer cells selectively. Fluorescent labeling of AA005 was successfully accomplished by a bioactivity assessment‐aided protocol after examining a number of potential derivative positions in parallel. AA005‐flu was found to exhibit similar cell selectivity to its parent molecule AA005. Fluorescent images of AA005‐flu show a significant difference in drug distribution between cancerous and normal cells, with accumulation of AA005‐flu occurring in the mitochondria of cancers cells.

Development of a Microreactor for Amino Acid Polymerization
Authors: Miyazaki M. , Honda T. , Nakamura H. , Maeda H.
Published: January 2007

A microreaction system consisting of a micromixer and a capillary reaction component was developed for the continuous production of amino acid polymers. A silicon glass based chip‐type micromixer tethered with a three dimensional microchannel network was fabricated by a combination of maskless technique, dry‐etching, and sequential anode bonding. The microreactor was constructed by connecting the micromixer with a microcapillary reaction component and a syringe pump. The resulting microreactor showed excellent controllability of molecular weight distribution of polyamino acid synthesis. The microreactor also produced amino acid copolymers with a more highly controlled molecular weight distribution than that of a batchwise reaction system operating for two months. These features demonstrate that the new microreactor is extremely suitable for the production of polyamino acids.
Controlled Hydrogen Oxidation in a Microstructured Mixer‐Reactor Module

Published: January 2007

For different applications it is necessary to perform a controlled oxidation of hydrogen. Apart from the safety‐relevant aspect, it can be also necessary to utilize as much heat as possible. The experimental results showed that hot spots and therefore thermal stress can be avoided with this new reactor concept. In addition, it has been demonstrated, that a cold‐start of such microstructured components is quick and stationary conditions are reached within less than 10 minutes in dependence of the reaction parameters. Conversions of hydrogen were in the range of 98 % when stoechiometric conditions or oxygen excess were applied. The temperature gradients and heat losses in the stationary mode of the operation of such catalytic burners were depending on the flow directions and parameters.
CO‐Bond Cleavage of Esters with a Naphthyl Group in the Higher Triplet Excited State during Two‐Color Two‐Laser Flash Photolysis
Authors: Cai Xichen , Sakamoto Masanori , Yamaji Minoru , Fujitsuka Mamoru , Majima Tetsuro
Published: January 2007

A CO‐bond cleavage of esters having a naphthyl group, NpCO‐OR and RCO‐ONp (Np=α‐ and β‐naphthyl (αNp and βNp, respectively), R=Ph and Me), was found during the two‐color two‐laser flash photolysis in acetonitrile. The CO‐bond cleavage occurred when NpCO‐OR and RCO‐ONp were excited to the singlet excited states (S1). On the other hand, no reaction occurred from the lowest triplet excited states (T1). When NpCO‐OR(T1) and RCO‐ONp(T1) were excited to the higher triplet excited states (Tn) using the second laser during the two‐color two‐laser flash photolysis, the CO‐bond cleavage occurred. The CO‐bond cleavage quantum yield (Φ) was estimated from the plots of the T1‐state esters disappeared within a laser flash versus the second laser intensities. The CO‐bond cleavage in βNpCO‐OPh(Tn) occurred more efficiently than in αNpCO‐OPh(Tn) and that in PhCO‐OβNp(Tn) occurred more efficiently than in PhCO‐OαNp(Tn). The Φ value for ester with Ph and β‐Np groups was larger than that for ester with Ph and α‐Np groups. The Φ value for MeCO‐OαNp(Tn) was similar to those for PhCO‐ONp(Tn), while that for MeCO‐OβNp(Tn) was much smaller than those for PhCO‐ONp(Tn) and MeCO‐OαNp(Tn). On the other hand, no CO‐bond cleavage was observed in NpCO‐OMe(Tn). The Φ value depended on the characters of the groups (Np, Ph, and Me) on the ester. Whether R is Ph or Me with or without π electron, respectively, is important for the CO‐bond cleavage. In other words, electronic delocalization of the Tn state including Np and ester groups is necessary for the occurrence of the CO‐bond cleavage in NpCO‐OR(Tn) and RCO‐ONp(Tn).
Dipyrrolyl‐Functionalized Bipyridine‐Based Anion Receptors for Emission‐Based Selective Detection of Dihydrogen Phosphate
Authors: Plitt Patrick , Gross Dustin E. , Lynch Vincent M. , Sessler Jonathan L.
Published: January 2007

New cationic anion receptors, based on the use of pyrrole‐substituted bipyridine and coordinated to transition metals, are described. Specifically, polypyridine–ruthenium and –rhodium cores have been functionalized to generate an anion binding site. The design was chosen to probe the influence of the pyrrole‐to‐pyrrole separation on anion‐binding affinities and selectivities; this distance is greater in the new systems of this report (receptors 1 and 2) relative to that present in related dipyrrolyl quinoxaline based receptors 3 and 4. Solution‐phase anion‐binding studies, carried out by means of 1H NMR spectroscopic titrations in [D6]DMSO and isothermal titration calorimetry (ITC) in DMSO, reveal that 1 and 2 bind most simple anions with substantially higher affinity than either 3 or 4. In the case of chloride anion, structural studies, carried out by means of single‐crystal X‐ray diffraction analyses, are consistent with the solution‐phase results and reveal that receptors 1 and 2 are both able to stabilize complexes with this halide anion in the solid state.
